High Wear Resistance

The initial hardness of high manganese steel products HB280-420 much higher than ordinary sand casting products HB189-230, can effectively curb the initial running parts wear, keep the machine precision design. In the harsh operating environment, the impact of the strong impact of the wear and tear, the surface structure of the phase transformation, the formation of dislocation hardening layer, continuous resistance to wear, to maintain the normal operation of equipment.
