ASTM A749/A749M-14(2021) - 1.9.2021
 
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 A1018/A1018M), cold-rolled carbon steel strip (Specification A109/A109M), high-strength, low-alloy cold-rolled steel (Specifications A606/A606M and A1008/A1008M) or cold-rolled high carbon steel (Specification A684/A684M).

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 E29.

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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

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.

1.8?This 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.
