【Abstract】 In this paper, a trial research for replacing cast steel 35Mn track shoe of blasthole drill is made. The test results of the chemical composition of the new material, mechanical properties, microstructure, heat treatment and wearing test in laboratory are involved; the wearing surlace figure of test sample with SEM has been observed and discassed too. The paper points out the optimum chemical composition of chromium-manganese series low alloy cast steel.更多还原
