Taking the alloying method, which is added vanadium, molybdenum, titanium and other alloy elements to ordinary steel , based on the super high manganese , through alloying and modification, grain refinement, improves impact hardening speed and impact hardening hardness. Its average of wear resistance is 50% more than the Mn13 , and toughness is equivalent to Mn13.
    Composite hammer, hammer handle using low alloy, high strength, high toughness; hammerhead using wear-resistant materials, give full play to the two materials technology advantage. Using composite technology being combined both together, expands the scope of application of high wear-resistant materials, and the service life is greatly improved.
