How much is the high manganese steel hardness ?

Mn13 high manganese steel hardness : its surface hardness from HB200 quickly lifted to more than HB500, This results in a high abrasion resistant surface layer, while the steel plate inner austenite still maintains good impact toughness.

Mn13 Special Characteristics :Mn13 is the best choice for strong impact resistance, high pressure material wear and other wear-resistant materials, with Work hardening characteristic that other wear-resistant materials can not be compared to, in the larger impact load or the role of greater contact stress, plate surface production hardening

Application of Mn13 high manganese steel plate:Wear-resistance steel for scale board of shot-blasting machine ,scale board of ball crusher; ball grinder ,bucket lip of grab, bridge steel plate, automobile frame steel plate, Jaws of crushers, hammers of pulverizers , cutting edges of large excavators, liner of shot blasting units, screens, shot blasting cabinets and furniture, anti-drill plate, magnetic separators and the metal. Recent years, more and more high manganese steel plates are used in maglev train, bullet-proof car, steel safe, rock drilling robot, new type tank and so on.

Chemical Composition of high manganese steel: C:0.90-1.20, Si:0.30-0.80, Mn:11.00-14.00, P:≤0.035, S:≤0.030
