| Abstract: | This paper discusses briefly the behavior of residual elements in steel and their effect on property of steel.The contents include:the source of residual elements in steel;solidification segregation or grain boundary segregation of residual elements during casting or heat treatment;the effect of residual elements on the surface hot shortness,the second temper brittleness,the corrosion resistance,strain aging and inhibition on grain growth.At last,it is pointed out that the production clean steel should be one of important projects for China Steel Industry in the future. |
