Manganese Steel Casting

Manganese Steel Casting

Nanjing Manganese Manufacturing.; Ltd (MGS Casting) starts to manufacture high manganese steel since 1985 years.The manganese steel is a unique alloy with high toughness, ductility, high work hardening capacity, non-magnetic in nature and usually good resistance to wear. Manganese Steel’s ability to work hardening is unique and probably has no equal in this respect. manganese Steel is used extensively in the field of Mining, Cement, Earthmoving, Mineral Processing, Oil Well Drilling, Railroading and Power Sector.

Our manganese steel casting products include cone crusher bowl liner, cone crusher mantle, jaw crusher plates, liner plate, shredder wear parts, blow bars and so on.

High Chrome Steel Casting


Impact crusher high chromium blow bars ensure the highest possible wear life is combined with mechanical reliability and numerous mounting possibilities. Thanks to the accurately balanced structure, the MGS Casting chromium blow bars are easy and economical to install.

With chromium steel, the carbon is chemically bonded in the form of chromium carbide. The wear resistance of chrome steel is based on these hard carbides of the hard matrix, whereby the movement is hindered by offsets, which provides for a high degree of strength but at the same time less toughness.
