LIU Xiang-hua, LU Jiang-xin, ZHANG Pi-jun, DU Lin-xiu, WANG Guo-dong ng 110004, China)  
Using the same chemical compositions as those of the cleanly plain carbon steel, by means of optimizing the parameters in rolling and cooling, the super steel which has fine grain size was produced. It will become the new generation steel product because of its advantages of low cost and good properties. Following this idea, the super steel with yielding strength of 400~500 MPa has been put into mass production, and the strip coils have been used to press as the auto beams. The research and development, production and application in industry of super steel in China and outside were described. Some problems in the production of super steel were discussed.
