HIGH-STRENGTH STEEL SHEETS FOR AUTOMOBILE BODY PANELS

The overall suitability of various steels (strain-aging steels such as capped nitrogenized and rephosphorized steels, killed rephosphorized and microalloyed steels) for automobile body-panel applications is assessed by comparing their characteristics with the performance requirements (formability, weldability, paintability, etc.). Of the different types of 40- to 50-ksi steels reviewed the killed rephosphorized steels (especially a silicon-containing version) show the best combination of formability and weldability. Although some difficulty in meeting paint-performance requirements has been recently reported with these steels, additional studies are needed to identify those factors that determine paintability in the killed rephosphorized steels.
