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.
