SAE J2340 Steel Sheet

What is SAE J2340?

SAE J2340 steels are dent-resistant, high-strength and ultra-high strength commonly used in the automotive industry. SAE J2340 constitutes seven grades of continuously cast high strength automotive sheet steels that can be formed, welded, assembled, and painted in automotive manufacturing processes. 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 organic compounds normally applied by coil coating. 

Grades and strength levels are achieved through composition and processing. The selection of grade should be based on part configuration and strength, as well as the amount of strain induced by forming and the impact strain has on the strength achieved in the finished part. 

SAE J2340 – XF grades are available with about 5% higher formability at each strength level. Steel Warehouse will gladly help you select the exact grade for your needs.
