Abstract

Automotive company has been endeavoring to develop high strength steels to get higher fuel efficiency of car since the oil shortage in 1970s and to cope with the recent strict environmental regulation. Outer panels(Hood, Roof, Door and Fender) for automobile require higher dent resistance. Bake-hardenable(BH) steels are known as useful for their high deep drawability and high dent resistance. Recently BH steels are increasingly adapted for outer panel use due to their high drawability and high dent resistance. In this study effect of temper rolling on formability (textures, r value) and bake hardenability is investigated fur improving characteristic of bake-hardenable steels.
