摘要

The product system of high strength low alloy steels (HSLA) produced by Wuhan Iron and Steel (Group) Corporation (WISCO) was presented. A series of high performance structural steels have been developed for important construction projects around the world in different areas, such as bridge, pressure vessel, pipe line,shipbuilding, architecture, machinery and railway wagons. In order to promote the development of large heat input welding steel, high grade thick pipeline steel and long span bridge steel, a lot of advanced production technologies have been achieved through intensive investigation, such as the control of high purity, high homogenization and free defects in steel slabs, the rules of high melting point particle formation and distribution in micro and nano scale during steel production, and the TMCP technology for ultra low carbon bainite steel for medium and heavy plates. WISCO will carry on research and application of economic and weather-resistant steels and promote the developing and producing technologies of HSLA steel.
