Abstract:

In order to satisfy the requirements for saving energy and safety regulations, evolution has been occurred for the last several decades in steels for automotive body and chassis. Among many kinds of advanced high strength steels (AHSS), multi-phase steels like dual phase steel, TRIP steels, and hot stamping steels are already commercialized and TWIP steel is expanding its use in complex automotive parts. After the introduction of the 3rd generation of automotive steel sheets in 2006, many efforts have been made for the development of medium Mn multi-phase steels in Korea as well as other countries like Japan, China and Europe. In this presentation, many kinds of AHSS which are being used or being developed will be introduced based on their microstructure and properties. In addition, the strong points and weak points of each steel will be explained. Finally, challenges from other materials are also introduced.

 

Key words: Austomotive steels, AHSS, multi-phase, TWIP, hot stamping
