High strength, high toughness:

In the quenching process of the high manganese steel liner, the special dual-medium quenching agent with good thermal stability is used as the medium to make the product achieve the combination of high strength, high hardness and high toughness to meet the technical requirements of wear resistance

High cost performance, strong adaptability:

The high manganese steel liner is processed by advanced technology. It has the characteristics of high quenching hardness and high toughness value, so that the high manganese steel liner has good wear resistance. Compared with the ordinary liner, the high manganese steel liner performs Outstanding price-performance ratio. It can adapt to mine wet grinding, dry grinding, mixed grinding, etc.
