Wear Resistance Steel Sheet MN13
Mn13 steel plate wear resistance analysis
High manganese wear-resistant steel Mn13 is an effective and objective choice of wear-resistant materials such as strong impact resistance and wear of large pressure materials
Wear-resistant materials can not match the work hardening characteristics, under the action of greater impact load or greater contact stress, steel plate surface production
Raw work hardening, the surface hardness from HB200 rapidly increased to HB500 or more, resulting in a high wear-resistant surface layer, and steel
The inner plate austenite still maintains good impact toughness.
Mn13 steel plate characteristics
There are two characteristics: first, the greater the external impact load, the higher the wear resistance of its own surface; The second is the gradual hardening of the surface layer
Wear, new work hardening layer will be continuously formed.
