(For Private Circulation)

Dear Members and Readers,

Happy to see another wonderful informative issue of METALL being released by our chapter.

Nice teamwork and very nice pictures. reetings to all the cited achievers.

In recent months, we have been motivated by visits of a Vice President IIM and a former

President IIM. Let us work hard to honour the commitments made by the chapter to these

IIM dignitaries. Let us also work hard on the Prof BPMMQ 2017. We should mentor the

school students. We should organize a few technical training programmes / short term

courses during 2017 - 2018. May be, follow up the recent suggestions from members, for

conducting SOJOM, joining hands with IWS. Let us also try to enhance the financial strength

of the chapter.

Last, but not the least, we should nominate capable members of our chapter for

consideration for awards of the IIM and NMD.

Best wishes,

(Prof S Raman Sankaranarayanan)

Good Evening sir,

I am very glad to see this Dec 2016 issue of metals, thanks for the hard work of the technical team make it

so colorful with lot of information. Next issue it would be better to reserve one page to publish about metal

related article from members or in general about mechanical properties of metals, etc... like that

something related to metals would make more meaningful of this metal issue.

Learnings from Fabrication ofT 23 (2.25 Cr-1.6 W-V-Nb) Steel Tubes in Power Plant Applications

R. Easwaran General Manager, Welding Research Institute & Labs, Bharat Heavy Electricals Limited

Tiruchirappalli, India - 620014

1.0 INTRODUCTION

It is widely accepted that Coal will continue as the fuel contributing maximum share towards the installed capacity for at least up to 2050, as per several reports. To keep the environmental issues under control, several efforts are on towards clean coal technologies, minimising CO2 emissions and other environmental impacts. Towards improving the efficiency of newer thermal power plants in India, the sub-critical thermal power plants are being phased out by super critical power plants exceeding 225 kg/cm2 pressure and ultra-super critical power plants with main steam temperatures over 600 °C. Many countries are carrying out research on Advanced Ultra Super Critical (AUSC) power plants with main steam temperatures of over 700 °C and pressures of over 300 kg/cm2. With these innovations, the efficiency of thermal power plants is expected to be in the range of 46-50 %.

The typical thermal power station has a boiler island which converts water to steam, superheaters that superheats the steam, steam and power piping which carries steam to the steam turbines and the steam turbine island that generates power. When we talk about moving to higher efficiency power plants, the crux of the development is in the materials (and their fabrication processes) to be used in all these islands, to withstand higher temperatures, higher pressures, oxidation, exfoliation, creep fatigue, thermal fatigue, corrosion in fuel water environments and so on. Ultimately, the candidate materials have to be made available at reasonable costs in all product forms with ease for welded manufacturing at shops and also for fielding fabrication.

In the last two to three decades, there have been significant advancements in the ferritic steels used for boiler applications, so much so that a new breed of Creep Strength Enhanced Ferritic (CSEF) steels have emerged and these have been extensively used in thermal power plants.

The major advancements have been in the 2.25 Cr-1 Mo, 9 Cr-1 Mo and 12 Cr segments of materials. One such advancement in the 2.25 Cr-1 Mo segment has been T 23 tubes, which find applications in the evaporator panels and superheater / reheater coils.

In our own experience, T 23 material in super critical power plants are used in roof panels, corner panels, burner panels and ash hopper regions. Butt welding of these tubes in panel form under site conditions as indeed challenging, considering the high restraints involved in

METALL Mar 17

the field assembly. In the event of a leakage, significant difficulty is there in the repair at such panels. The fins on either side of the joint have to be cut, the leaking weld joint has to be replaced with a tube spool inserted, which makes it two butt joints, the joints have to be heat

treated, fins have to be re-welded with PWHT. Thus this takes enormous time.

The material T 23 is essentially 2.25 Cr-1.6 W-V-Nb material and is incorporated in ASME as Code Case 2199-6. Essentially T 23 is a low alloy steel derived from SA 213 T 22 (2.25 Cr-1 Mo) by substituting Mo content with W and adding Nb, V and B. Mo and W act to strengthen the material matrix. V, Nb and Ti form fine precipitates (carbides and nitrides), which provide the obstacles for dislocation movement, thus increasing mechanical and creep resistance of the material. B stabilises M23C carbides, by retarding their coarsening. Typical CCT Diagram, chemical composition, mechanical properties are given in Figure 01.

1.1 ASSUMPTIONS DURING INTRODUCTION OF T 23

When T 23 was introduced, there were quite a few assumptions, which made the material truly

attractive. The nine major assumptions are listed below:

1. Material will be low carbon bainitic 2. Steel may not require normalising in the shop floors 3. Normalising T 23 steel is a simple process 4. Steel is not prone for brittle failures 5. The steel does not require preheat and post weld heat treatment

METALL Mar 17

6. Steel is not prone for cold cracks, as hardness will never reach 350 HV in as-welded condition

7. Steel is not prone for Stress Relief Cracks

8. Steel is not prone for Restraint Cracks 9. Steel is not prone for Corrosion Assisted Cracks

The material has been used across the world and the actual experiences have shown that these are not necessarily true. This is not to undermine the fantastic efforts taken in developing, testing and launching these materials, but to bring forth the fact that field fabrication conditions of these power plant materials are indeed rigorous. In fact, in simple butt welds between tubes, the welds do behave just as predicted. But, say for example in fabrication of these tubes in panel form involving field erection, the assumptions turn out to be myths. A strong effort was taken to understand through experimentations at WRI and practical experience in shop floors / field fabrication, how the material behaves differently from the assumptions

1.2 Myth # 1: Material is Bainitic

One of the expectations was that T 23 material will always end up with a bainitic microstructure in weld and HAZ under the typical welding conditions. Gleeble studies at WRI clearly indicate that bainitic structure is observed only in the broad range of cooling rates from austenitising temperatures of 20 °C / sec to 0.5 °C / sec. When the cooling rates is 1 °C / sec or less, ferrite starts appearing in the HAZ of the material. Similarly when the cooling rates are 50 – 100 °C / sec, there is clear evidence of martensitic structures. CCT diagram for HAZ generated in Gleeble is shown in Figure 02 below. Dilatograms and microstructures also validated this.

Gleeble simulated specimens were also impact tested after subjecting to different cooling rates and the fracture appearance is seen to be varying from cleavage to ductile dimple type. The typical hardness values obtained after different cooling rates are also different. It can be

METALL Mar 17

clearly seen that T 23 material is likely to produce different microstructures, quite different from bainitic, depending on the actual cooling rates and this can produce martensitic structure
