Standard Specification for Steel, Sheet, Carbon, Structural, and High-Strength, Low-Alloy, Hot-Rolled and Cold-Rolled, General Requirements for
ABSTRACT
This specification covers the general requirements for carbon, structural, and high-strength, low alloy steel sheets in coils and cut lengths. The steel sheets shall be manufactured by hot-rolling, cold-rolling or temper rolling. Cold-rolled sheets shall undergo annealing after being cold reduced to thickness. Products shall undergo cast or heat analysis, product, check, or verification analysis, and sampling. Product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, vanadium, columbium, niobium, titanium, aluminum, and nitrogen. Mechanical properties of the materials shall conform to the following properties: tensile strength, yield strength, and bending strength. Thickness, length, width and flatness tolerances and allowances for cold-rolled and hot-rolled sheets are indicated. Steel may be produced as ingot-cast or strand-cast.
SCOPE
1.1 This specification covers the general requirements for steel sheet in coils and cut lengths. It applies to the following specifications that describe carbon steel, structural steel, and high-strength, low-alloy steel (HSLA) furnished as hot-rolled sheet and cold-rolled sheet: Specifications A 414/A 414M, A 424, A 606, A 659/A 659M, A 794, A 1008/A 1008M, A 1011/A 1011M, and A 1039/A 1039M.
1.2 This specification is not applicable to hot-rolled heavy-thickness carbon sheet coils (Specification A 635/A 635M).
1.3 In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification.
1.4 For the purposes of determining conformance with this and the appropriate product specification referenced in 1.1, values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E 29.
1.5 Annex A1 lists permissible variations in dimensions and mass (see Note 1) in SI [metric] units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to Annex A1 is mandatory when the “M” specification is used.
Note 1—The term weight is used when inch-pound units are the standard. However, under SI the preferred term is mass.
1.6 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.7 This specification and the applicable material specifications are expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.
