Materials | Manganese steels
Standard manganese steel is suitable for applications where gouging abrasion is predominant. Furthermore, it is recommended for environments where gouging and grinding abrasions occur together. Manganese steel is characterized by high strength; toughness and excellent work harden ability by impact and gouging. Manganese steel also has excellent resistance in metal to metal wear.

High manganese steel can provide a higher life time in special environments and reduce overhaul periods.
