High manganese steel ball mill liner plate in general refers to a kind of casting steel with the Mn content at 10-15%, the carbon content at 0.9-1.5%, mostly higher than 1.0%. Under low impact load, can achieve HB300-400, high impact load, can achieve HB500-800 Different impact load, the surface hardening layer depth can be up to 10-20 mm. Hardened layer with high hardness can resist impact and reduces abrasive wear. Under the condition of strong impact abrasive wear, high manganese steel has excellent wear-resistant performance, so it is widely used in Mining, Building Materials, Coal industries as wear-resistant parts. But, under the condition of low impact load, the characteristics of high manganese steel can't display due to the strain hardening effect is not obvious.
