SAE J2340_201703 defines and establishes mechanical property ranges for sevengrades of continuously cast high strength automotive sheet steels that can be formed, welded, assembled,and painted in automotive manufacturing processes. The grade of steel specified for an identified part shouldbe based on part requirements (configuration and strength) as well as formability. Material selection shouldalso take into consideration the amount of strain induced by forming and the impact strain has on the strengthachieved in the finished part. These steels can be specified as hot-rolled sheet, cold-reduced sheet,uncoated, or coated by hot dipping, electroplating, or vapor deposition of zinc, aluminum, and organiccompounds normally applied by coil coating. The grades and strength levels are achieved through chemicalcomposition and special processing. Not all combinations of strength and coating types may be commerciallyavailable. Consult your steel supplier for details.
