【Abstract】 The chemical composition,microstructure and mechanical Properties of the testing cast steel are introduced in this paper. The smelting and heat treatment process is put forward. Industrial testing shows that the relative wear resistance of the low alloy martensitic cast steel mill liners is 1.5 time longer than that of high manganese cast steel mill liners.更多还原
