Abstract： |
Hongkang bainite steel is smelted by using Mn and Si as main alloy elements and Cr, Ni, Mo and other elements as supplementary material. After being austenitized and air cooled, composite bainite/martensite texture is obtained. The steel of the present invention is mainly used for railway frog and may be also used in other parts needing high abrasion resistance and shock resistance. |
