    1. Scope

    1.1 This specification covers the general requirements for hot-rolled steel strip in coils and cut lengths. It applies to carbon steel and high-strength, low-alloy steel furnished as hot-rolled.

    1.2 This specification is not applicable to hot-rolled heavy-thickness carbon sheet and strip coils (Specification A 635/A 635M), cold-rolled carbon steel strip (Specification A 109/A 109M), high-strength, low-alloy cold-rolled steel (Specifications A 606 and A 1008/A 1008M) or cold-rolled carbon spring steel (Specification A 682/A 682M).

    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 under 2.1, 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 (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 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.

    1.7 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.
