Причина отмены

This specification covers quenched-and-tempered carbon steel and high-strength low-alloy steel plates of structural quality for welded, riveted, or bolted construction.

Formerly under the jurisdiction of Committee A01 on Steel, Stainless Steel and Related Alloys, this specification was withdrawn in October 2010. This standard was withdrawn without replacement due to its limited use by the industry.

Реферат

This specification covers quenched-and-tempered carbon steel and high-strength low-alloy steel plates of structural quality for welded, riveted, or bolted construction. The plates shall undergo heat treatment by heating to a temperature that produces an austenitic structure. Heat and product analyses shall be performed on the material and shall conform to the required amount of chemical composition in carbon, manganese, phosphorus, sulfur, silicon, vanadium, columbium, nitrogen, and copper. The plates shall withstand tension test and applicable grade shall conform to the specified mechanical properties such as yield strength, tensile strength, and elongation.

1.1 This specification covers quenched-and-tempered carbon steel and high-strength low-alloy steel plates of structural quality for welded, riveted, or bolted construction.

1.2 If the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be used.

1.3 Plates under this specification are available in four grades as follows:

^A Varies with thickness. See Table 1.

1.4 The values stated in either inch-pound units or SI 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 is to be used independently of the other.
