1.1 This specification covers high-strength, low-alloy, hot-rolled steel sheet and strip and cold-rolled sheet having improved formability when compared with steels covered by Specifications A 606 and A 607. The product is furnished as either cut lengths or coils and is available in four-strength levels, Grades 50, 60, 70, and 80 (corresponding to minimum yield strength (see Table 1)). The steel is killed, made to a fine grain practice, and includes microalloying elements such as columbium, titanium, vanadium, zirconium, etc. The steel may be treated to achieve inclusion control. The product is intended for structural and miscellaneous applications where higher strength, savings in weight, improved formability, and weldability are important.
1.2 The values stated in inch-pound units are to be regarded as the standard.
