High Manganese Plate & Sheet
High Manganese Steel Plate – 11-14% Manganese Plate
The High Manganese Grade Plate 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 whilst retaining its tough interior.
The Ultimate Work Hardening Steel (11-14% MN / 1% C)
General Information of Manganese Steel :
Manganese is a “Work Hardening” steel commonly referred to as “AUSTENITIC 11-14% Manganese”. Manganese is produced to the original “Hadfield Specification” which guarantees optimum wear and work hardening properties. It is “non magnetic”.
Manganese Advantages :
WORK HARDENING refers to the fact that the steel becomes harder and harder the more it is impacted or compressed.
The “Hadfield” grade has an original hardness of approximately 220 BRINELL. With continued impact and /or compression it will surface harden to over 550 BRINELL.
It should be noted that only the outer skin surface hardens. The under layer remains highly ductile and tough. As the surface wears, it continually renews itself becoming harder and harder.
Manganese steel is an austenitic steel which means it is non-magnetic. This property makes it useful in many applications such as bottom plates for lifting magnets – separator drum shells for magnetic materials – wear shoes on electric brakes etc.
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 underlay not work-hardened maintain a very high resistance to shock.

Typical Uses:
The rapidity with which Manganese Plate hardens make this steel grade suitable for applications where the components must resist wear under conditions of sliding contact, often coupled with heavy pressure and repeated impact. Typical applications are wearing plates, stone or iron chutes, industrial track work, anti drill plates such as security doors, shot blasting equipment and tumbling machines.
Manganese Plate is the ideal solution for cases where severe wear is combined with shocks or high pressure capable of work-hardened its austenitic structure. Used in jaws of crushers, hammers or pulverizers, cutting edges of large excavators, liners of shot blasting units, cores and wall of parpen moulds, and screens.
