This specification covers the standard for cold rolled ultra high strength carbon steel sheet in coils or cut lengths. The sheet shall be produced from aluminum killed steel and shall undergo continuous annealing to austenitic temperatures and then be water quenched. Cast or heat analysis shall conform to the prescribed chemical composition requirements in carbon, manganese, phosphorus, sulfur, and aluminum. Tension test shall be done on the point immediately adjacent to the material to be tested and properties shall conform to the specified tensile strength. The sheet shall have a matte surface finish texture and shall have cut edges. Unless otherwise specified, the sheet shall undergo oiling.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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.
