High Manganese hammer mainly used in the field to withstand shocks, extrusion, and etc bad working conditions.
The most important characteristic of high manganese hammer is under the condition of strong shocks extrusion, the surface of the hammer will rapidly appear hardening phenomenon, makes it hearts remained austenite of good toughness and meantime the hardening layer with good wear resistance. This is not possible for the other material. But the wear resistance of high manganese hammer is only under the condition of have enough power to form the hardening surface, otherwise the performance is very poor.
