Standard Specification for Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Carbon, Commercial, Drawing, Structural, High-Strength Low-Alloy, High-Strength Low-Alloy with Improved Formability, and Ultra-High Strength
ABSTRACT
This specification covers standards for hot-rolled, heavy-thickness steel sheet and strip coils. The materials shall come in the following designations: (a) Commercial Steel (or CS) of Types A and B, and Standard Steel Designation; (b) Drawing Steel (DS) of Types A and B, and Standard Steel Designation; (c) Structural Steel (SS) of Grades 30[205], 33[230], 36[250] in Types 1 and 2, and 40[275]; (d) High-Strength Low-Alloy Steel (HSLAS) of Grades 45[310], 50[340], 55[380], 60[410], 65[450], and 70[480] in Classes 1 and 2; (e) High-Strength Low-Alloy Steel with Improved Formability (HSLAS-F) of Grades 50[340], 60[410], 70[480], and 80[550]; and (f) Ultra-High Strength Steel (UHSS) of Grades 90[620] and 100[690], Types 1 and 2. The strip and sheet coils shall conform to specified limit in width and thickness. Carbon, manganese, phosphorus, silicon, aluminum, silicon, copper, nickel, chromium, molybdenum, columbium, titanium, nitrogen, and boron contents shall be followed as specified by each designations, classes, types, and grades. Tension tests shall be performed. Materials shall adhere to yield strength, tensile strength, and elongation requirements. Guidelines for workmanship, finish, and appearance are given.
SCOPE
1.1 This specification covers hot-rolled, heavy-thickness coils beyond the size limits of Specification A 1011/A 1011M.
1.2 The product is available in six designations: Commercial Steel, Drawing Steel, Structural Steel, High-Strength Low-Alloy Steel, High-Strength Low-Alloy Steel with Improved Formability, and Ultra-High Strength Steel.
1.3 This material is available only in coils described as follows:
ProductSize Limits, Coils Only Width, in. [mm]Thickness, in. [mm] StripOver 8 to 12, incl
[Over 200 to 300]0.230 to 1.000, incl
[From 6.0 through 25] SheetOver 12
[Over 300]0.230 to 1.000, incl
[From 6.0 through 25]
Note 1—The changes in width limits with the publication of A 635/A 635M – 06a result in a change in tensile testing direction for material from 0.180 in. [4.5 mm] to 0.230 in. exclusive [6.0 mm exclusive] over 48 in. [1200 mm] wide as that material is now covered by Specification A 568/A 568M – 06a. The purchaser is advised to discuss this change with the supplier.
1.4 Sheet and strip in coils of sizes noted in 1.3 are covered by this specification only with the following provisions:
1.4.1 The material is to be fed directly from coils into a blanking press, drawing or forming operation, tube mill, rolling mill, or sheared or slit into blanks for subsequent drawing or forming.
1.4.2 The material is not to be converted into steel plates for structural or pressure vessel use unless tested in complete accordance with the appropriate sections of Specifications A 6/A 6M (plates provided from coils) or A 20/A 20M (plates produced from coils). Plate converted from coils is no longer governed by this sheet steel specification and since this material is now a plate, the requirements of the appropriate plate specification shall apply, except in cases where there is a conflict between the requirements of the plate specification and this specification. In these cases, the more restrictive limits of either specification shall apply.
1.4.3 The dimensional tolerances of Specification A 635/A 635M are applicable to material produced to this specification.
1.4.4 Not all strength levels are available in all thicknesses. The user should consult the producer for appropriate size limitations.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
