GENERAL POLICIES

If material appears to be defective, the customer shall attempt to process the material as usual. If the material appears to have numerous imperfections or defects af-ter a minimum of 10% has been processed, the customer may then suspend production and notify AHMSA, and a technical service representative will arrange to inspect the material. The customer shall notify AHMSA of any technical or ad-ministrative claims via www.ahmsa.com or customer ser-vice representative. Once a claim has been initiated, the Sales and Technical Service departments will be notified in order to seek resolution.

AHMSA shall not be held responsible for certain claims arising from the oxidation of our products. Discoloration and staining is inherent from the presence of atmospheric humidity and the collection of condensation in transit. Be-cause of the reactivity of steel, oxidation may be present between the layers in coils or between bundled sheets. AHMSA shall not be held responsible for the following oxi-dation claims:1. When material is ordered without oil (dry) or without a

suitable surface treatment.2. When orders specify packaging with less than AHMSA’s

approved minimum level of protection.3. When the steel is stored outdoors, or if left unprotected

against moisture or sudden temperature changes.Note: If upon delivery the steel coil temperature is below the warehouse temperature, the customer shall not unpack the material until the coil temperature equalizes with the warehouse.

A variation up to + /- 1% of the scale weight per invoiced shipment shall be allowed between the customer and AHMSA, before a claim may be initiated. Will be considered in the following cases:1. Upon delivery, all items have immediately been inspec-

ted for the presence of moisture in the package.2. If moisture in the packaging is present at the time of

delivery, an annotation must be made in the delivery log while in the presence of the carrier. AHMSA sales must then be notified immediately.

3. Before the material is delivered to the customer or the customer’s contracted carrier.

For material that is picked up by the customer, the claim must be made to the customer’s contracted carrier. AHMSA sales must then be notified immediately.

AHMSA guarantees the surface of the hot rolled coil to be 98% free from defects such as: mechanical marks, scratches, scale, laminations, flakes or cracks that do not affect the thickness tolerance. For special requirements, a production feasibility study shall be required.Flatness 6 months Hot rolled steel coils that have not been skin passed are guaranteed to meet 50% of the ASTM A-568 & A-635 standard. See the Flatness tolerance information listed in Table 13.8 of this manual. 45 days Skin passed, hot rolled steel coils are guaranteed to have a maximum of 1/4” wave height per meter.

The remaining 2% length of coil shall be within 100% of the tolerance standards. Width (mill edge): guaranteed to be -0”/+0.500” of specification, in 98% of the length of the coil. The remaining 2% length of coil shall be within 100% of ASTM A-568 toleranceTelescoping Until Permissible Ranges: Maximum telescope of 2”, maximum coil misalignment of& alignment received 1”, and coil misalignment for HSLA of 1.5”.

Hot rolled steel coils that are not pickled (dry) are manufactured with a mill edge in thicknesses from 0.059” to 0.500” and widths from 29” to 63.750”. Specific grade sizes can be referenced in size tables 1 through 5 of this section.

The surface finishes of hot rolled coils are semi-smooth and may have oxidation.Hot rolled coils are used for structural applications or where the surface quality is not critical. The typical applications of AHMSA steel coils include heavy machinery wear parts, crossties, pipes, and tubes.

When the application requires a quality surface finish or painting, such as in the automotive industry, pickling or another cleaning process should be performed by the customer, or the customer should consider purchasing AHMSA’s pickled steel coils.

COLD ROLLED FLAT PRODUCTS

AHMSA’s cold rolled flat products comply with the highest quality standards in the international steel industry. All processes and departments are governed by the AHMSA Management System which complies with ISO 9001, ISO 14001, and OS-HAS 18001.

Our Cold Roll mill processes are certified under the abovementioned quality stan-dards and also comply with the international standards ISO/TS 16949 and ISO-14001 that are more commonly applied to the automotive industry. By meeting these certifications, we are able to present an added value to our customers by ensuring quality management of the processes while at the same time, guarantee-ing environmental protection during the manufacturing process.

AHMSA offers cold rolled sheet, in grades and specifications which cover most steel applications such as motor lamination or for use in the automotive and home appliance industries. AHMSA also offers coated products in grades and specifica-tions designed for use in the metallic container industry.

Steel grades presented in this manual represent our main product lines. Some products, sizes, and grades require a minimum volume to manufacture and/or are subjected to restrictions.

For any application not covered in this manual, please contact a technical consultant.




AHMSA’s cold rolled sheet is supplied in coils, cut to length sheets, slit width coils or strips with the following characteristics:

• Annealed or not Annealed (Full Hard) • Tension Leveled or not Tension Leveled • With or Without Anticorrosive Coating • Oiled or Dry • Matte or Bright Finish

Material edges are cut during the pickling process, prior to cold reduction. Tempered and Tension Leveled material can be ordered with a trimmed edge, which is cut during the tension leveling process.

The coil weights should range from 5 to 20 metric tons.

Packaging Methods: All coils are protected with V.C.I. wrapping unless intended for Ma-ritime transport, in which case the edges and outside diameter of the coils are protected with steel covers. Shipment Method: By Tractor Trailer (20 mt/unit) or by Railroad Car (80 mt/unit). For volume orders consideration will be given for multiple weights.

TABLE 3 SURFACE TYPE

Used for exposed parts or when the surface texture, surface condition, flatness, and ductility affect the quality of the end product.Used for unexposed parts or where surface texture, surface condition, or the appearance is not important to fi-nished product. This class of material is also used where maximum formability is desired.

Processed to meet requirements for controlled surface texture and flatness limitations.

Coil must be expected to contain minor sur-face imperfections such as pits, scratches, edge breaks, cross breaks, roll marks and other minor surface imperfections and major surface imperfections such as holes and loose slivers.

The magnetic field cores of electrical equipment consist of pilings of steel sheets stamped to size and shape necessaries form a core. For maximum electrical efficiency, cores must be made of material having good magnetic properties, in particular, high permeability and low core loss.

Permeability: Is the relative ease in which material becomes magnetized. For steels produced in AHMSA, guarantee is of 2,000 Gauss/Oersted minimum.

Core losses: Is the quantity of electric energy dissipated as heat when steel is magne-tized by alternated current. Its units are watt/lb or watt/kg.

Semi processed (non-oriented grain) electrical steels: This material does not have fully developed magnetic characteristics, it requires of an annealing process done by the costumer, usually after the stamping to develop the desired magnetic properties. This steel can be supplied in a range of physical and mechanical characteristics and can be matched to specific customer stamping and annealing practices.

When the storage time is nearing a six-month period, a hardness increase of 1 or 2 points can be expected.

When the storage time is nearing a 2-month period, a hardness increase of 1 or 2 points can be expected. Store in covered warehouse and keep a relative humidity less than 75%. Original mill packing not damaged or removed. Don’t subject the coil to sudden temperature changes. Unpack after the coil is at room temperature to prevent conden-sation and subsequent oxidation problem. Claims will not proceed if: The tested chromium levels in the surface of the client’s sam-ples indicate normal passivation (0.35 mg/ft2 minimum). The relative humidity of the warehouse is high (> 75%). The original packing is removed or damaged (applicable to the rejection of batches of coils). The cut to length sheets from the coil are not stored with proper packaging for a period exceeding one month. These conditions will cause discoloration by tin oxidization. Tin Plate coil production in continuous mill lines does not allow for the removal of non-compliant sheets, therefore, during cutting, the non compliant sheets shall be separated from the cutting line for evaluation. According to the Tables 18 and 19. Roughness range specified in Tin Plate corresponds to the base steel surface finish; in finished product it can vary, depending on the coating layer (ASTM A-624, section 5.2).

GLOSSARY

It would take a whole book to define all the terms used in connection with the manufacture, sale, and use of steel products. However, the following definitions are limited to the more common terms which can be useful for our customers and sales people alike. We recommend that you consult a book titled, “The Making, Shaping, and Treating of Steel” if you are interested in collecting more technical knowledge beyond what we have defined.

AGING Changes in physical and mechanical properties that occur when low carbon

steel is stored for a period of time. Aging is also accelerated by exposure of steel to elevated temperatures. Stretcher strains and fluting can result from aging.

ANNEALING A process of applying heating and cooling to Hot Rolled and Cold Rolled Sheet

products to induce softening.

BASE BOX An area unit equivalent to 112 sheets 14 x 20 in.

BASE WEIGHT Nominal weight in pounds per base box is an approximate thickness measu-

rement. The Tin Plate ordered for its thickness equals the unit weight per base box.

BUNDLE Consists of ten packages which are 1,120 sheets/packages.

CAMBER Camber is the deviation of a side edge from a straight line. It is the measurement

being taken on the concave side with a straight edge.

CARBON STEEL Steel which owes its properties primarily to carbon without substantial amount of

other alloying elements: Steel is classified as carbon steel when the maximum content does not exceed the following percentages: Carbon 0.50%, Manganese 1.65%, Silicon 0.30% and Copper 0.20% (when specified).

CCT Full Hard steel with tension leveling process.

CTT Cold roll steel (tempered), with tension leveling process.

COIL BREAKS Creases or ridges which appear as parallel lines, transverse to the direction of

rolling. They generally extend the width of the sheet.

COLD ROLLED PRODUCT Flat rolled products for which the required thickness has been obtained by

rolling without heating at room temperature.

COMMERCIAL QUALITY STEEL (CQ OR CS) Steel of this quality is for uses involving simple bending or moderate drawing.

Commercial quality sheet can be bent flat upon itself in any direction at room temperature.

CORROSION Gradual chemical or electrochemical attack on metal by atmospheric moisture

or other agents.

CUTTED EDGE Side cutting on the pickled and hot rolled process.

DEEP DRAWING QUALITY STEEL (DDS) DDS is manufactured when Drawing Quality (DS) won´t provide a sufficient

degree of ductility for fabrication of parts. Deep Drawing Quality requires that the sheet be free from aging and uses special killed steel. This quality is made by special steelmaking and processing practices.

DRAFT Reducing thickness of strip by hot or cold rolling.

DRAWING QUALITY STEEL (DS) As compared to Commercial Quality steel, Drawing Quality steel has a greater

degree of ductility and is more consistent in performance. This greater ductility and uniformity are a result of higher production standards, selection and pro-cessing of the steel.

ELECTROLYTIC CLEANING LINE Electrolytic cleaning process for cold rolled steel.

FULL HARD Cold reduced sheet that has not been annealed.

FULL HARD FULL HARD Cold reduced sheet that has not been annealed, where stiffness is required.

HAR Floor plate in coil.

HOR Hot roll coil, mill edge.

HOT ROLLED This term describes flat steel products that are produced to finished size by

rolling at high temperatures.

HOT ROLLED CUT TO LENGTH SHEET (ORH) Cut to length sheets from Hot rolled, mill edge coils, available in light and heavy

thicknesses.

HRO Wide Plate Steel.

HRP Hot rolled pickled and oil or without oil.

KILLED STEEL Steel deoxidized by silicon or aluminum to reduce the oxygen content to a

minimum so that no reaction occurs during solidification of the metal.

LAMINATIONS Imperfections resulting from the presence of blisters, seams or foreign inclu-

sions. These are sometimes visible on the surface of the metal.

LUBRICITY Otherwise known as slipperiness, it is the ability of steel sheet to slide on forming

dies.

MILL EDGE (OM) Normal rounded edge produced in hot rolling of flat steel.

OILED Application of a suitable rust inhibitive oil applied to flat rolled steel in the effort

to retard rusting. When surface finish is important, the oil helps to reduce friction scratches that may develop in transit. The oil coating is not intended to serve as a lubricant for subsequent fabrication.

PACKAGES A unit quantity of 112 sheets for Tin Plate product.

PICKLING Removal of mill scale or oxidation by immersion of steel into a dilute solution

bath of hydrochloric acid. The steel is then rinsed, dried, and is oiled (as re-quested).

PITTING Is a form of extremely localized corrosion that leads to the creation of small

cavities in the metal.

PROFILOMETER An instrument that measures surface-roughness height in micro-inches. The

height is measured as the absolute deviation from a mean surface.

QUALITY Refers to accuracy of the steel for the purpose or purposes for which it is in-

tended (See Commercial Quality, Drawing Quality, and Structural Quality).

ROUGHNESS Surface finish or Surface texture of the steel which form on the surface of hot

steel. GLOS

SCALE Typically called Mill scale, is defined as a surface layer of primarily ferric oxide

that forms on the exterior of steel or iron when hot.

SLAB A semi-finished steel block having an oblong cross-section in which the width is

at least twice its thickness. It differs from a bloom which has a square or nearly square cross-section.

STIFFNESS The physical property of being inflexible and hard to bend.

STRUCTURAL QUALITY When other values of mechanical properties are specified, tests are required

to verify the mechanical specifications such as tensile strength, yield point, and elongation.

TENSION LEVELING The process to improve flatness, the strip is under great tension with a slight

elongation above the yield point of the material, and simultaneously leveled. The material is shape corrected and relieved of most internal stresses.

TEMPERING A series of heat treatments to “toughen the metal”. In doing so, the temper

process provides a matte or bright surface finish and improves the flatness of the steel.

TCO Tin Plate in coil.

TFS Tin Free Steel. (Electrolytic chromium plate).

THEORETICAL WEIGHT A calculated weight based on nominal dimensions and steel density of 0.129

kg/in3 (7.85 gr/cm3) for plate, coil and sheet products.

TOLERANCE Specified limits of deviation from a dimension.

TRIMMED EDGE Side trimming on the Tension leveling process.

TRIMMED EDGE (TIN PLATE OR TIN FREE STEEL) Side trimming on the Plating process (Tin Plate or Tin Free Steel).

WELDING Fastening two pieces of metal together by softening with heat and applying

pressure.
