1.1 This specification covers hot-rolled, heavy-thickness coils beyond the size limits of Specification A 1011\/A 1011M.<\/p>\n
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..<\/p>\n
1.3 This material is available only in coils described as follows:<\/p>\n
Note 1The 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.<\/p>\n
1.4 Sheet and strip in coils of sizes noted in 1.3 are covered by this specification only with the following provisions:<\/p>\n
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.<\/p>\n
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.<\/p>\n
1.4.3 The dimensional tolerances of Specification A 635\/A 635M are applicable to material produced to this specification.<\/p>\n
1.4.4 Not all strength levels are available in all thicknesses. The user should consult the producer for appropriate size limitations.<\/p>\n
1.5 The values stated in either inch-pound units or SI units [metric] are to be regarded separately 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.<\/p>\n
