Recent Development of Hot-Rolled AHSS for Lightweight Chassis

Abstract:

The development of ultra-high-strength automotive steel sheets for lightweight automobiles is still an effective strategy from the material point of view. In the case of cold-rolled steels for BIW(Body In White), it has been a long time since steel with 980MPa of UTS or higher were commercialized, and the use of 1.2GPa and 1.5GPa of cold-rolled steels is also increasing. However, in the case of hot-rolled steel for chassis, the increase in strength is not as fast as that of cold-rolled steel, because chassis parts are the lower structure of a vehicle and are very sensitive to durability.
