By mechanical test, electrochemical test, and impact corrosion wear test, the combination properties, the impact corrosion and abrasion properties, and the mechanism of the low carbon CrNiMo steel and the high manganese steel used as lining board steel were investigated. The results show that the combination property of the low carbon CrNiMo steel is better than that of the high manganese steel. The impact corrosion and abrasion properties of the low carbon CrNiMo steel is also better than that of the high manganese steel at the same low impact energy.
