日本神户制钢所为适应汽车减轻自重的需要,开发出汽车部件用的冲压成形性和焊接性俱佳的新一代高强度热轧钢板,已开始正式向汽车部件厂商销售。这种神钢独自开发的热轧高强度钢板具有铁素体、贝氏体和马氏体3种组织,故称作“三相钢板”,在减轻汽车自重需求高涨的情况下其作为部件用钢的需求可望扩大。神钢早在10年前就着手三相钢板的开发 Kobe Steel, Japan to adapt to the needs of vehicles to reduce their own weight, the development of automotive components with excellent press formability and weldability of a new generation of high strength hot-rolled steel plate has begun to formally sell to auto parts manufacturers. This Kobelco-developed hot-rolled high-strength steel with ferrite, bainite and martensite three kinds of organizations, it is called “three-phase steel”, reducing the weight of cars in the case of high demand as a component The demand for steel is expected to expand. Kobelco embarked on the development of three-phase plates as early as ten years ago
