High-manganese steel liner: it has a certain impact toughness. When impacted, the surface will produce cold hardening, tough and wear-resistant, with a hardness of HB300-350, an impact value of 700Nm/cm2, and a total life of about 5000-6000 hours. The high-manganese steel liner is commonly used in medium and small ball mills.
