1.1This specification covers hot-rolled, heavy-thickness coils beyond the size limits of Specification A1011/A1011M.
1.2The 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.
1.3This material is available only in coils described as follows:
| Product | Size Limits, Coils Only | |
| Width, in. [mm] | Thickness, in. [mm] | |
| Strip | Over 8 to 12, incl | 0.230 to 1.000, incl |
| Sheet | Over 12 | 0.230 to 1.000, incl |
Note 1:The changes in width limits with the publication of A635/A635M – 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 A568/A568M – 06a. The purchaser is advised to discuss this change with the supplier.
1.4Sheet and strip in coils of sizes noted in 1.3 are covered by this specification only with the following provisions:
1.4.1The 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.
1.4.2The 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 A6/A6M (plates provided from coils) or A20/A20M (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.
1.4.3The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specification.
1.4.4Not all strength levels are available in all thicknesses. The user should consult the producer for appropriate size limitations.
1.5The 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.
1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
