The excellent fine primary structure with less defects and lower composition segre- gation is obtained through modification for medium-manganese wear-resistant steel , then high im- pact toughness and wear-resistance is obtained by quenching from as-cast and obvious comprehen- sive techno-economic effect is gained with energy saving.

Based on the above,the disadvantage of high manganese steel and its investigation direction at present were presented and also the alloy design and microstructure design of low and medium wear resistant alloy steel were discussed.
