Description of crusher hammer head :

High chrome hammers: while casting, we not only add molybdenum, vanadium, titanium, nickle, boron and other rare alloy elements. Meantime, we specially adopt variety of alloy modifier to strengthen the matrix. Those hammers use refining, vacuum casting, directional solid and etc technical’s’ to increase the grain refinement and make the hammers performance achieve the best performance.
