This SAE Recommended Practice defines various grades of continuously cast high-strength sheet steels and establishes mechanical property ranges. These sheet steels can be formed@ welded@ assembled and painted in automotive manufacturing processes. They can be specified as hot-rolled or cold-rolled sheet. Furthermore@ they can be coated (hot-dipped galvanized@ hot-dipped galvannealed@ and electrogalvanized) or uncoated. Not all combinations of strength@ dimensions and coatings may be commercially available; consult your steel supplier for details.
