High manganese steel is made by alloying steel, containing 1.17 to 1.25% carbon, with 13 to 21% manganese.
High manganese steel is unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up to three times its surface hardness during conditions of impact, without any increase in brittleness which is usually associated with hardness.

High manganese steel has been used in the mining industry, cement mixers, rock crushers.
We can supply the Mn13, Mn18 and Mn21 high manganese steel concave, mantle, bowl liner. The concave, mantle, bowl liner use on Metso, Sandvik ,Symons and other cone crusher to crusher stone
