  Under certain working conditions, impact crusher hammer high manganese steel is difficult to form an effective hardened layer, abrasion resistance is low, life is very short. Select joint 4 C Mo steel in the crusher hammer as the material and determine its heat treatment process and measures to make the hammer has good hardness, toughness and wear resistance, obtained from a better economic 2r Benefits. Through the new hammerhead do wear properties, hardness and surface-phase analysis of the organization can draw significantly improved the wear resistance of the new hammer, hammer high manganese steel materials can be used as a substitute.
