1. Scope

1.1 This specification covers hot-rolled heavy-thickness carbon-steel sheet and strip of structural quality in coils beyond the size limits of Specification A 570/A 570M. This material is intended for structural purposes where mechanical test values are required and is available in the sizes listed below. This material is available only in coils as described below:

1.1.1 The following grades are covered in this specification:

1.2 The values stated in either inch-pound units or SI (metric) units 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. Combining values of the two systems may result in nonconformance with this specification.

1.3 Sheet and strip in coils of the sizes noted in 1.1 can be included in this specification only with the following provisions:

1.3.1 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),

1.3.2 This specification is not applicable to the steels covered by Specification A 635/A 635M,

1.3.3 The dimensional tolerances from Specification A 635/A 635M are applicable to material produced in accordance with this specification,

1.3.4 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, and

1.3.5 Not all strength levels are available in all thicknesses. The user should consult the producer for appropriate size limitations.
