Wear-resistant alloy steel mainly by adding Cr, Mo, V, Ti, rare earth and other elements to the traditional composition of high manganese steel to improve the performance, of which Cr is particularly widely used. In the process of work hardening of high manganese steel, dynamic variational aging, that is, C- Mn atomic pairs, is formed, which has the clustering effect of expanding the C- Mn ordered atomic pairs in high manganese steel. In this paper, the changes in the organization, structure, resistance and wear resistance of wear-resistant alloy steel and ordinary high manganese steel with different tempering temperatures are studied. The results show that the wear-resistant alloy steel is better than ordinary high manganese steel under the condition of relatively low carbon content. Moreover, according to the tempering temperature, the structure of the alloy high manganese steel is different, and the wear resistance is also different.

In the process of surface treatment of special wear-resistant alloy steel, the physical and chemical characteristics of the surface material of the product are greatly changed by the interaction of external input energy, alloy elements or materials with the surface of the product. The microscopic nature of surface treatment is the controllable physical and chemical changes on the surface of the material, which has excellent properties different from gases.
