Improvement of fuel economy, crash worthiness and passenger safety are gaining increasing attention in the automobile industry. Kobe Steel has developed and has continued to produce a variety of high strength steels for automobiles including 590MPa class, dual-phase hot dip galvannealed steel and hot & cold rolled TRIP-aided steel. This article introduces some of these new products including a very ductile 980MPa class hot dip galvannealed steel and an ultra-high strength, cold rolled, steel with excellent delayed fracture resistance. Some technological features of this steel grade are presented, including formability, spot-weldability, and dynamic strength characteristics. The development status of Hi-Tens for a variety of needs is discussed. With enforcement of regulations for environmental protection and crash worthiness, technologies to reduce vehicle weights will progress and Hi-Tens will expand their applications. Kobe Steel will continue to develop high performance Hi-Ten products and application technologies that meet the requirements of automobile and parts manufacturers and thus contribute to environmental protection and crash worthiness.
