Cold Rolled ASTM A-1008

This specification covers cold-rolled, carbon steel sheets, in coils and cut lengths, in the following designations: commercial steels (CS Types A, B, and C); drawing steel (DS Types A and B); deep drawing steel (DDS); extra deep drawing steel (EDDS); structural steel (SS Grades 25, 30, 33 Types 1 and 2, 40 Types 1 and 2, 50, 60, 70, and 80); high-strength low-alloy steel (HSLAS Classes 1 and 2 of Grades 45, 50, 55, 60, 65, and 70), high-strength low-alloy steel with improved formability (HSLAS-F Grades 50, 60, 70, and 80); solution hardened steel (SHS); and bake hardenable steel (BHS). Conformance of the steel sheets to chemical composition requirements shall be tested by heat analysis. Specimens shall also undergo tension and bending tests and shall conform to specified values of tensile and yield strength, elongation, and bake hardening index. Unless otherwise indicated, sheet surfaces shall have a matte finish and shall be oiled.
