Abstract

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. Hot-rolled material shall be furnished hot-rolled, not annealed, or pickled. The chemical composition shall be in accordance with the applicable product specification. Where the material is used for fabrication by welding, care must be exercised in the selection of chemical composition or mechanical properties to ensure compatibility with the welding process and its effect on altering the properties. A heat analysis shall be conducted to determine the percentage of elements specified or restricted by the applicable specification. The specimens shall be subjected to bend and tension tests.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

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 1The 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.
