| Impact wear in corrosive condition is the main environment that wet grinding liner works in. During the using processing of the liner and grinding balls, they bear both impact wear of abasive materials and corrosion slurry, and the interaction of three makes the abrasion more serious. Comprehensive performance of traditional liner like high manganese steel, medium carbon alloy steel etc. cannot meet the requirements. But the development of low carbon high alloy steel have provided quite a good solution for this problem.Nickel is unique in improving properties of alloy steels, but also expensive and limited in resources. This research wants to obtain better cost performance liner steel materials by adjusting the nickel containing and manganese containing in addition of keep service performance if possible.Select suitable heat treatment crafts for three liner materials and analyze their microstructure, mechanical properties and uniform corrosion resistance. The results indicate that the final microstructure of three kind of materials are all martensite, and the comprehensive performance decreases by the increasing of manganese containing.Impact wear properties of alloy liner steels with different composition in corrosive condition were investigated in MLD-10 tester, selected two impact energy. The results indicate that the low carbon high alloy steel has the best wear-resistance performance, but the alloy liner which containing 1.0% nickel and 1.5% manganese has the best cost performance. Wear mechanism of three kind of alloy liner are also discussed in this paper.
