The new materials for ultra-light steel auto- body (ULSAB) and their new technologies of heat treatment are introduced, especially the development of advanced high strength steels ( AHSS) and the continuous annealing technology. The new materials of special steels for auto components and their heat treatment technology are outlined, including bearing steels, gear steels and spring steels.
