Development of Hot-Rolled Sheet Steel with the Significant Increase in Tensile Strength Induced by Strain Age Hardening

Shinjiro Kaneko; J. Hiramoto; Saiji Matsuoka; Akio Tosaka; Kei Sakata

A new type of bake-hardenable high strength hot-rolled sheet steel was developed, which shows remarkable increase in tensile strength as well as yield strength after strain age hardening without addition of special elements. The new sheet steel possesses excellent crash-worthiness and high fatigue strength, and also shows good formability almost equal to that of conventional high strength sheet steels. This unique combination of properties makes it possible to reduce the weight of the car body by using thinner gauge material when the new sheet steel is applied to crash-resistant parts and underbody parts.
