Nb application to automotive steel sheets

International Symposium on Niobium Microalloyed Sheet Steel for Automotive Application

The automobile and steel industries are closely linked by a strong customer – supplier relationship. The application of high strength sheet originated from social needs. The keen issue for automakers in recent years has been to reduce the weight of the automobile body while maintaining sufficient safety by using high strength steel sheet to ensure both fuel efficiency and crash worthiness. The characteristics of the steel sheets for an automotive body have changed drastically according to changes in demand. In this paper, the exact metallurgical background and mechanical properties of hot rolled steel sheets used for chassis and cold steel sheets used for body are introduced. (AU)
