Energy forever

EnErgy is thE lifEblood of our society today. in fact, it is challenging to come up with areas of modern life that could exist without energy.

WhilE trEmEndous progrEss has been made in energy efficiency, the growing population and rising living standards demand more energy – and cleaner energy. reducing energy-related greenhouse emissions is key in mitigating the threat of climate change.

As An industry, energy is facing major challenges as well as opportunities. oil has become harder and more expensive to find and extract, yet considerable deposits still exist. renewable energy sources such as wind and solar power will also play a larger role in the future.

WE nEEd to pursuE all sources of energy just to keep up with the demand, while ensuring reductions in emissions. We also need technology and material innovations to meet both the energy and the climate challenges. at outokumpu, we want to be part of this. Whether for oil pipes, nuclear plants or wind mills, we can offer stainless steel that is long lasting, durable and fully recyclable – enduring even the most extreme environments.

EnErgy is A kEy thEmE for this issue of Forever, and every day in our business. We will also explore this theme further at the outokumpu experience in Berlin. i look forward to witnessing the great energy that i know our experts and customers can create together!

Markus Moll If there is one sector of the global economy that holds sway over all the others, it is energy. From evolutionary changes in power production techniques to sudden shocks in the fossil fuels market, developments in the energy sector have far reaching – and often unexpected

– consequences. For that reason, keeping track of the ever-changing energy picture is key to getting a grasp on what is happening just about everywhere else.

Oil price taking a nosediveMarkus Moll is Managing Director and Senior Market Analyst with Steel & Metals Market Research, a firm that focuses on providing intelligence to the stainless and specialty steel industry. In his estimation, the sudden slump in oil prices is generally good news for the global economy, but also carries with it powerful and disruptive reverberations. The most immediate of them has been the major slowdown in exploration and development of new oil and gas fields.

“There are various analyses suggesting that around one trillion dollars of planned investments in hundreds of projects all around the world make no sense in the current price environment,” Moll says. Naturally, anyone involved in those areas of the energy sector is going to feel more than a pinch.

NORSOK material qualification opens new possibilitiesOutOkuMpu’s site in AvestA, sweden, has been qualified to deliver 2205, 2507, eDX 2304TM, 254SMO and4529 grades according to nOrSOK, an oil and gas industry application standard. The approval helps to meet the needs of existing customers who value high quality enduring materials, as well as to serve new potential customers.

“The nOrSOK standard puts high demands for the mate-rial properties, such as corrosion resistance and microstructure. From the producer, the nOrSOK standard requires, for example, process stability and ability to do heat treatment within a narrow temperature range,” says Cecilia Lille, project leader for the nOrSOK approval team at Avesta, Sweden.

Audit by customerreaching the required material properties and acquiring the qualification is the result of the persistent work of the Avesta team. An audit in the nOrSOK standard approval process is always done by a customer. For Avesta, the auditor was Aker Solutions, an engineering company from norway. The audit process consisted of carefully following the material process route and a detailed examination of the heat treatment.

After the approval, the oil industry giant Statoil added Avesta to their list of fully qualified nOrSOK suppliers. Many smaller companies and distributors follow the Statoil list and only buy nOrSOK approved material.

However, a bigger – and more positive – story could come from the expected boost in the rest of the economy. “Lower oil prices are like a big tax cut for consumer goods,” Moll says. “People have more money in their pockets. They are spending more on other things.”

Moll notes that the current oil price situation and the resulting market dynamic are, by their nature, likely to be relatively short-term phenomena, not least because of the combined effects of field depletion and growing oil consumption. The more complex question is what is happening in electricity production.

the winding road to renewablesAway from the hunt for oil and gas, the main headline maker in the energy sector is the shift toward using renewables, most notably in electric power generation. In Europe and the US in particular, governments are leading the drive with ever-tighter emissions regulations and renewables targets.

The result is that sustainable forms of power generation like wind and solar are growing faster than their more traditional rivals. Moll points out, however, that the move toward renewables is fairly irregular and complicated, with no obvious, financially viable solutions to some of the technical challenges posed.

For one, wind and solar have to be balanced to fill in the peaks and troughs they create on a power grid. Plants using gas-fired turbines would offer a good, relatively clean-burning solution, “but it's not particularly booming because utilities know these plants need to be running at least 4,000 hours per year,” Moll says. “One of these big units costs 400 million dollars. It's a risky investment.”

Coal still a contenderComplicating matters further is a phenomenon called ‘clean’ coal, which is fairly controversial.

“The industry is showing the progress it has made in reducing flue gasses and increasing efficiency, and at the same time there is a strong lobby showing coal burning as one of the main emitters of CO2 and SOx,” Moll explains. Which lobby is stronger, he says, depends on which country you're in.

Indeed, geography and politics do seem to be major factors in how the move toward renewable energy is playing out. Some countries in Asia and elsewhere, where energy demand is growing, may be more inclined to use and improve coal technology rather than abandon it in favor of investing in more sustainable alternatives.

“In general I would say that the coal-fired power plants still have a great future in China, India and Russia, and in some of these emerging countries like Indonesia, where coal is available. They may still build a big number of new, ultra-critical or even super-ultra-critical coal-fired power plants,” Moll says.

That is a completely different dynamic to Germany, for example, where a powerful anti-coal lobby holds sway. Moll also predicts that the days of large coal-fired plants are over in the US.

the stainless steel connection The reality, of course, is that fossil fuels will eventually run out, forcing the complete transition to renewable energy sources. How soon that would happen and what advances in renewables are around the corner are both unknowns.

With that in mind, what can be said about the role of stain-less steel in the changing energy picture?

Volume-wise, Moll points out, wind and solar plants actually use far less stainless steel than the old-style coal-fired and nuclear plants with their high-temperature boilers. But in fact, all forms of power plants rely on stain-less for various applications, and it's clear that without stainless steel piping and other construction elements, neither wind nor solar power would be feasible.

Returning to the question of cheap oil, last year's dramatic price slide is expected to offer both positives and negatives for stainless use, just as it will for the economy at large, Moll says. It would mean a drop in demand for seam-less tubes and forged bars, the two stainless products that oil exploration and production uses far more than others. As with the economy at large, stainless should be helped by the increase in consumer spending.

“When people are spending more on other things, it should also increase the use of stainless,” Moll says. And since consumer goods account for nearly half of the entire stainless market, stainless steel use should see an overall benefit from low-priced crude oil, according to Moll.

From a sustainability standpoint, any upward bump in the use of a long-lasting, recyclable product should be a positive thing. •

ENHANCED DESIGN -

No. Description Date

Once the buildings are complete in 2016, Baosteel’s landmark offices in Shanghai will have façade surfaces totaling 48,000 square meters. Designed by Pelli Clarke Pelli Architects (PCPA), the American firm behind

such iconic buildings as the World Financial Center in New York and the Petronas Towers in Malaysia, Baosteel offices require cladding of the highest quality.

In addition to the Shanghai project, the main building of the future Baosteel southern headquarters is being constructed in Guangzhou, and will rise to 140 meters tall.

Adapting to requirementsFor the new headquarters, Baosteel Group supplies the hot bands, while SKS processes 316L stainless steel into a Linen 25 surface finish. Through a joint venture between Outokumpu and Baosteel Group, SKS has helped deliver stainless steel cladding on a number of prestigious buildings, such as the Chemsunny World Trade Center in Beijing.

John Wu, Market Development and Research Manager, SKS, thinks it was ultimately the company’s ability to listen carefully and to adapt that allowed SKS to stand apart from local competitors.

“The selection rounds were strict and our product was chosen after the third round of trial production,” Wu says.

Strong and sustainableThe quality of the stainless steel coil plate was also an important factor. “One of the advantages of Linen 25 is that it is good at preventing glare,” says Zhang Yiming, Technical Manager, SKS. “The material is not very shiny, making the reflection level acceptable. This is one of the reasons Linen 25 is an attractive surface finish for designers.”

While it is industry standard to have the decorative finish polished into the surface of the coil, the Linen 25 pattern is rolled onto the surface.

“It hardens the coil’s surface to a degree not matched by traditional decorative finishes, making Linen 25 more resistant to scratches and lowering the need for mainte-nance,” Yiming says. “Of course it is also a beautiful finish,” he adds. •

Outokumpu’s FDXTM stainless steel grades combine the high strength of duplex stainless steel with high ductility levels. This makes them comparable

to the austenitic stainless steel grades that have so far most typically been used for challenging applications where the formability of the steel is at a premium.

The FDX grades have raised plenty of interest for applications including flexible pipes, water tanks and plate heat exchangers. “But we soon realized that our customers in other demanding market areas such as pump manufacturers would also benefit from solutions that combine the formability of austenitic steel grades with the strength and durability of duplex grades,” explains Ramin Moshfegh, Senior Specialist, Forming and Virtual Product Development at the Avesta Research Center.

A tough challenge for steelmakersPumps often have to function under very harsh conditions in terms of pressure, temperature, wear and corrosion risks. The FDX grades are an answer to these challenges.

“It’s crucial for pump manfacturers that these properties of FDX all combine to greatly increase the overall durability and service life of their pumps, and thus reduce the need for maintenance,” says Moshfegh.

Novel formable duplex (FDXTM) stainless steel grades are proving to be well suited to demanding applications such as pump casings, where the formability of the stainless steel is a vital asset alongside strength, durability, and resistance to wear and corrosion.

FDX gradesfavorable for pump components

BuilT To lasT

In many respects, pump chambers, which are manufactured through a complex process involving multiple steps, have presented Outokumpu with the ulti-mate test of the material formability of their FDX grades.

Formability tried and tested with pilot customersDanish pump maker Grundfos has been seeking out new options for pump casing material for their wide range of submersible pumps. Important applications for such pumps include groundwater intake, irrigation systems, the dewatering of mines and construction sites, fish farm facilities, fountains and offshore installations. A strong and durable duplex stainless steel would clearly fit the bill for challenging environments like these, as long as the material could be suitably formed to precise specifications.

The tests carried out by Outokumpu and Grundfos confirmed the impressive formability of FDX for manufacturing pump casings on a commercial scale.

“The results were consistent, with the final strength of the product significantly increased. Our customers have described the outcome as very promising,” says Moshfegh. “They are now able to see how they can produce the same components with both higher strength and better corrosion resistance than before.”

Opportunities for cost savingsMoshfegh is convinced that the positive findings will also enable manufacturers to develop pumps that can reliably withstand harsher operating conditions. These include environments of high pressure, heavy wear and extreme temperature variations, as well as high salinity levels in marine applications.

“Another benefit of using high-strength material like FDX is that it gives manu-facturers an opportunity to downgauge the dimensions of steel components, and produce light-weight pumps that can save on both material and space,” explains Moshfegh. This option to downgauge can result in considerable cost savings, as well as greater freedom for technical design.

From the lab into the real worldAccording to Moshfegh, the unique combination of properties is due to the favorable microstructure and chemical composition of Outokumpu's FDX grades. The ductility of the new grades is particularly attributable to a phenomenon known as the TRIP effect, standing for Transformation Induced Plasticity. The TRIP effect is achieved by using a cold forming method that enhances the strength and formability of the stainless steel.

The test findings have also shown that manufacturers will be able to use the same forming tools earlier used with the


FDX grades

standard austenitic grades, after making minor alterations regarding pressing force and the use of lubricants.

“The findings show that our FDX grades have a unique combination of properties. No one else currently produces grades like these as commercially available products for important markets and applications where such solutions now represent key advantages,” Moshfegh adds. •

Reference to the more detailed technical paper describing the findings from the testing of FDX steel grades in pump casings, available online

• www.outokumpu.com/white-papers

outokumpu first launched the new FDX 25™ and FDX 27™ duplex grades in May 2013, after developing them for four years at the company’s avesta Research Center in sweden. The FDX grades offer good resistance to localized and uniform corrosion. at the same time, they have proven

to be as durable as existing high-strength duplex grades. Furthermore, the FDX grades have been seen to offer all the other typical benefits of duplex stainless steels, including mechanical strength up to twice that of austenitics, and good resistance to stress and corrosion.

Properties of FDX increase the overall durability of pumps, reduce the need for maintenance and offer greater freedom for technical design.

Nirosta’s transformation process towards having more flexibility in all its units is in full swing. “After visiting our five locations in Germany, I am very certain that we can quickly achieve clear results with our realignment within the

market. The changes we are making should become more noticeable for our customers.”

For Oliver Picht, the already initiated strategic and structural changes are the new foundation, while well-trained and motivated teams are the keys to success.

Focus on the customerPicht believes that Nirosta will set itself apart from the competition by offering service that is both optimized and individualized.

“For years now, many of our customers, for example in the automotive industry or in the white goods segment, have increased their level of services to their customers. Customers require that their suppliers take the same approach,” says Picht. “Nirosta will rise to the challenge.”

He is convinced that the joy of work means clear understanding of what every employee does for the customer. “Our employees are passionate and very proud of their customers and want Outokumpu to be viewed as being best in class,” he points out.

Active forces of changeCooperation between departments is a great positive force for the ongoing changes, but “the transformation will still take time to complete.”

“We are restructuring Outokumpu Nirosta – reorganizing, consolidating, and simultaneously making investments in new machines and equipment to further optimize the production of ferritic grades in Nirosta. Our target is to become an even higher performing manufacturer of stainless steel products and a better employer,” says the new head of Nirosta.

Service that showsHe compares the transformation process to a shipping industry. “We are transforming a large tanker into a maneuverable yacht. Upon completion of the transformation process, Outokumpu Nirosta will be an agile partner that will be able to take advantage of its strengths in serving its customers.”

As one possibility, he views a model of different service packages. “We must offer our customers the required product selection and the most optimal service in order to meet their specific needs. Everything counts: including availability, packaging types as well as offering a customer-specific service.”

For Picht, gaining an edge over the competition is often decided far apart from the products and services offered. Instead, it often comes down to knowing the customer and being able to optimally support him with his business activities. This is where motivated teams throughout the entire supply chain will make a difference. •

Finnish company, Langh Group Cargo Solutions, chose Outokumpu’s new high-chromium austenitic grade Outokumpu 316plus ™ (also known

as Outokumpu 4420) for their new tank and special cargo containers. As the name suggests, the new grade’s proper-ties are even better than 316(L). Because it contains less nickel and molybdenum, it is a competitive alternative for 316(L).

Product Manager Markku Yli-Kahri shares his view on 316plus.

How did you learn about 316plus?Langh Group Cargo Solutions manufac-tures special portable containers for cargo and portable tank containers for liquid transportation in ships, trucks or on trains. Over the years, we have deve loped and improved the containers and the trans-port methods. Our target in development is to build containers that speed up cargo loading and unloading times, optimize a vessel’s stability and keep the pro ducts undamaged during t ransport and loading.

316plus makes containers lastLangh Group Cargo Solutions needed a strong and durable material for their two container types. Product Manager Markku Yli-Kahri from Langh Group Cargo Solutions gives his insight on working with Outokumpu's new grade.

316plus

As stronger material, 316plus

allows for thinner walls of the container, which results in lighter weight and increased capacity.


The tank container will be on display at Outokumpu Experience in Berlin. Come and discuss with experts what the grade could offer for your business. • outokumpu.com/experience

When we were planning these containers, I was in discussion with Outokumpu and they brought up the new material as an alternative. We took the grade on board and the new tank container is made completely of 316plus. The special transportation container’s walls and floor are made of 316plus.

Why did you choose 316plus?We needed a strong material for a corro-sive environment. 316plus had a number of pro perties that made it appealing. It is stronger than 316(L) and has better corro-sion resistance. This means that we could make thinner walls for containers, which results in both a lighter weight for the container and an increase in the amount of material that can be carried. This is already a big benefit for us. When we add the attractive price to this, the offer was even more intriguing.

The special container will be used for transporting corrosive and sharp bulk materials. For this container, 316plus went through cold working to further increase the strength. The steel will not burst easily even if sharp objects are loaded into the container. This is a great improvement from a durability point of view.

What material have you used before for your containers?We have built the special containers with wear-resistant carbon steel before, but the combination of corrosion and wear resis-tance of 316plus was better. We have also worked with Outokumpu duplex grades for

certain containers, but for these containers the corrosion resistance of 316plus is good enough.

How did the material perform?It was a relief to know that handling and welding of 316plus was similar to standard grades we have worked with, and that we could use familiar tools and welding tech-niques in construction. This made the fabri-cation fast and easy. We didn’t notice any problems when welding and constructing the material.

At the time of the tank’s construction, 316plus was still in the process for stan-dard acceptance and we needed the official T11 and ADR approvals for the container.

Therefore, several new material tests were run by Lloyd’s Register. 316plus passed all the material tests without any problems.

The first experience of 316plus was posi-tive and we will continue to follow these containers closely to see how they perform during use. Our target is a longer container life cycle that will make the container even more cost efficient for us as a producer. •

316plus was accepted as UNS S31655 into the ASTM A240 standard in March 2015. Check the grade’s properties at SteelFinder on steelfinder.outokumpu.com.

316plus passed all the Lloyd’s Register tests without any problems.

It is not just another skyscraper. At 104 stories and 541.3 meters, it is not the tallest in the world (it is the fourth tallest), but it may indeed carry more symbolism than any other skyscraper on

the entire planet.One World Trade Center (1WTC) in

Lower Manhattan, New York City, is the architectural landmark created to replace the Twin Towers that were destroyed on September 11, 2001.

Opened in November 2014, it provides over 325,000 square meters of office, commercial and residential space. 1WTC also serves to memorialize the structure that preceded it.

Outokumpu covers the cornersArchitecturally, 1WTC presented many challenges. Not only were the regular challenges of skyscraper construction present, but there were elaborate security requirements, as well.

“The original structure had distinc-tive corners and the architects sought to echo these in highlighted corners on the new structure,” says Outokumpu Project Manager, Jörn Teipel.

Teipel is in charge of all architectural applications of stainless steel that are produced at Outokumpu Nirosta, including special surfaces. For the 1WTC project, a team consisting of members of application

technology, production, product service and a roll texturer were given the task to create a brand new surface.

Creation of Laser“In order to accentuate the corners,” says Teipel, “the architect requested a surface that would appear bright from whatever angle it was viewed.”

Outokumpu’s Linen finish would have been standard, but to make the corners appear prominent the architects required even more brightness, so Laser was created.

Laser is a pattern finish produced with an embossing process in the rolling mill. It takes its name from the structure on the roll, which is created with laser technology.

Two hundred tons of Laser-finished cladding, made in the Dillenburg plant in Germany, was delivered to the 1WTC site.

Stainless attracts attentionAlthough stainless cladding has been in use for around 100 years, its positive attributes keep it from going out of fashion.

“Competing materials are aluminum, plastics, concrete and stone, but in comparison, stainless is a generally very corrosion-resistant material,” says Teipel. “After cleaning, it has the same appearance as years before, a feature that is hard to achieve with concrete or plastics.”

Indeed. The stainless on the Chrysler

“ When you have a very matt finish, it can appear lifeless. Therefore, we need to develop dull surfaces with sparkle and liveliness!”

building in New York City, just six kilo-meters uptown from 1WTC, still looks good a full 85 years after its construction.

“Builders want the appearance to be constant over time,” says Teipel. “Architects like its ‘honest’ and ‘pure’ qualities, as well as its noble appearance. Stainless simply attracts attention.”

Matt with sparkleIn recent years, there have been glare issues with tall buildings in heavily urbanized areas, such as the Walkie-Talkie building (20 Fenchurch Street, London). This has led cities like Singapore to create legislation about curtain walls.

“We are asked more and more by archi-tects if we can supply duller finishes,” says Teipel. “When you have a very matt finish, it can appear lifeless. Therefore, we need to develop dull surfaces with sparkle and live-liness!” •

Two hundred tons of Laser-finished cladding, made in Dillenburg, Germany, was delivered to the construction site.

It was out-of-the-box thInkIng that led designer emelie ahlnér to develop the striking steel dress recently showcased at Swedish Fashion Week – a gorgeous, Gehry-esque swathe of matte mesh folds. The collaborative METMASK project emerged from a simple question: Could stainless steel exist as a lightweight material?

The idea was to explore knit metal as a lightweight design and improve upon existing steel mesh by creating a stronger, formable multi-layer material. The team of partners worked to produce a lightweight

316plus accepted into the ASTM A240 standardoutokumPu’s new addItIon to its product portfolio, the high-chromium austenitic 316plus TM (outokumpu 4420), has been accepted as UNS S31655 into the ASTM A240 standard from edition 15A on March 2015. ASTM A240 is the standard specification for chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications.

316plus is an enhanced version of 316(l) as it is stronger and its corrosion resistance is boosted by higher chromium and nitrogen contents.

Outokumpu Annual Report and Sustainability Report publishedIn 2014 outokumPu took a positive step forward. In the second year since the merger, tangible results of the strategy started to show: profitability was clearly improved, debt was reduced and a strengthened customer focus was reflected in improved delivery performance and the number of new customer projects. Work continues to return outokumpu back to sustainable profitability.

The year 2015 also marks a milestone for our sustainability reporting: it’s now 40 years since the first environmental report of outokumpu was published in 1975.

The significant investment Outokumpu has made in the environment over the past decade shows some impressive returns. Last year, according to

Juha Ylimaunu, head of sustainability and development at Outokumpu, the company's recycled content rate topped 85 percent, making Outokumpu the global industry leader in recycling.

In addition to recycling, Outokumpu continues the work to increase process effi-ciency, essentially trimming energy input and waste output wherever possible.

Turning by-products into resourcesThose efforts have paid off effectively in managing the slag, dust and scales that result from the production chain. This waste isn't actually waste at all, Ylimaunu points out.

At its melt shops in the US, UK, Sweden, Finland and Germany, Outokumpu, together with its contractors, extracts valuable alloying metals like nickel, chromium and molybdenum from the slag and returns them to the manufacturing

Outokumpu’s drive toward leaner stainless steel production continues by improving material and energy efficiency with recycling in the lead role.

“Finding pathways to efficiency goes hand-in-hand with investments to smoother operations,” says Juha Ylimaunu.

process. The company similarly pulls metal out of the dust and scales produced in steel making.

The bulk of what remains is used mainly for construction purposes like road struc-tures or in making asphalt. Outokumpu's Swedish plant, for example, converts part of its slag into mega blocks for wall construc-tion, while in the UK recovered brick waste is used as a substitute for dolomite.

In 2014, the company's Tornio, Finland, plant made history by reaching

a 100 percent use rate for its slag. It's a significant milestone on the road to achieving the ultimate zero-waste target.

Every watt countsEnergy use is another issue that is monitored closely, not only because of the power Outokumpu uses annually in steel production, but because of the carbon emissions associated with it.

Constant process improvements led to huge energy efficiency gains in recent years,

which helped to cut the amount of CO₂ emitted per tonne of steel produced by over half between 1997 and 2007. The company has set itself a goal to increase energy performance by ten percent and to shave another 20 percent from the CO₂ per tonne output over the 2009–2020 period.

“There is no magic way to decrease the CO₂ emissions. Finding new pathways to efficiency is more or less our daily work. It goes hand-in-hand with investments that target smoother operations,” Ylimaunu says. “For example, last year our Dillenburg cold rolling unit in Germany improved its energy efficiency significantly without any bigger investments.”

Knock-on savingsLooking at the wider economy and ecosystem, Ylimaunu stresses stainless steel is an inherently sustainable material that actually reduces emissions and saves energy. With stainless steel’s decades-long lifespan, strength and easy maintenance, it is ultimately a low-cost proposition.

Tanker trucks made with stainless are larger and lighter, leading to long-term fuel savings. Stainless is also critical to the existence of the renewable energy industry. It is used in solar energy projects and for higher wind power towers.

“As the vision of our company is to create a world that lasts forever,” Ylimaunu says, “we are producing this type of product and collaborating with other industries for sustainable innovation.” •

The recycled content rate in Outokumpu stainless topped 85 percent, making it the global industry leader in recycling.
