SAE J2340

Dent Resistant, High Strength, and Ultra High Strength Automotive Sheet Steel J2340_199910

Seven grades of continuously cast high strength automotive sheet steels that can be formed, welded, assembled, and painted in automotive manufacturing processes. The grade specified should be based on part configuration and strength.  Material selection should also take into consideration the amount of strain induced by forming and the impact strain has on the strength achieved 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 organic compounds normally applied by coil coating. The grades and strength levels are achieved through composition and processing.

SAE J2340 – XF grades are available with about 5% higher Formability at each Strength level.

We will be glad to help you select the exact grade for your needs.
