This high manganese grade is an excellent work hardening, abrasion resistant steel. This steel is a non magnetic austenitic type, supplied in full plates or as profiled pieces by plasma cutting. Suitable for wear applications where high impact/gouging abrasion leads to a work hardening effect.
High manganese steel plate becomes increasingly hard when the surfaces of components are subject to repeated impact or abrasion. Its toughness, derived from high tensile strength and ductility, enables shock leads to be absorbed safely. Lack of lubrication or the intrusion of grit or sand particles does not seriously impair the wearing surfaces of components in contact. These characteristics combine to make high manganese steel plate an ideal steel for use as wearing plates in those situations where abrasion, impact, or lubrication difficulties are encountered. The steel has the unique property in service of rapidly developing a work hardened surface while retaining its tough interior.
Wear Resistance of Manganese Plate
Severe wear on the surface has a work-hardening affect on the austenitic structure of this steel. This leads to an increase from the initially low hardness (about 200 BHN) to a service hardness of at least 500 BHN. This work-hardening maintains itself through in-service life. The underlays not work-hardened maintain a very high resistance to shock.
