Standard Specification for Steel, Sheet, Carbon, Ultra High Strength Cold Rolled
1.1 This specification covers a cold rolled ultra high strength carbon steel sheet in coils or cut lengths. The product is available in four strength levels. The steel's strength is obtained by water quenching from an austenitic temperature resulting in a martensitic microstructure. This product is intended for miscellaneous applications where ultra high strength, weight saving, and good weldability are important.
1.2 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.
