Page 1 Current Status of Advanced High Strength Steel for Auto-making and its Development in Baosteel Zhu Xiaodong Ma Zhaohui Wang Li (Baosteel research institute, Shanghai 201900, China) Abstract: Along with the intensifying of energy crisis and environmental problems, energy saving and safety have become the most important issues for auto-making industry. To achieve these goals, weight reduction is most effective, which leads to the fast development and application of advanced high strength steels. In this article the lightweighting project of automobiles and its major achievement are introduced, with emphasis on the availability, application and characteristics of advanced high strength steel sheets (AHSS). The current status of the equipment for AHSS production is briefed, and the development of AHSS in Baosteel is also covered. Key Words:automobile, lightweighting, AHSS 1 Introduction Along with the intensifying of energy crisis and environmental problems, energy saving and safety have become the most important issues for auto-making industry. Among the many measures in reducing gas consumption and emission, reducing the weight is the most effective ---10% of weight reduction will lead to 3%~7% less of gasoline consumption[1~ 3] . To reduce the weight of the vehicle and thus energy consumption, the proportion of high strength steel used in auto-making is gradually increasing. To address this tendency, the investment of steel industry on the development and re ...
