Development of advanced high strength steels for automotive applications

  • Y. S. Jin

Abstract

The big issues that the automotive industry confronts are those concerned with environment and safety. The
lightweighting of the autobody plays one of the key roles for the development of environment-friendly vehicles
through the improvement of fuel efficiency and CO2 reduction. Advanced High Strength Steels (AHSS) are
worth noticing as the most promising materials for the weight reduction of autobody with securing the
crashworthiness and cost competitiveness still more. Considering such significances of AHSS to both steel
makers and car manufacturers, some recent progresses are reviewed on the development of various steel types
of AHSS including TWIP steel, hot-dip galvanizing technologies to improve the coating quality, and the issues
for AHSS forming technologies by illustrating the noticeable activities.
