Compared with similar imported products, our impact crusher parts have many advantages, such as safety, wear resistance, low price, ect., and short delivery time.Impact hammer sells well in many countries.

Our blow bars produced using abrasion resistant high chromium white cast iron material. While producing:
1. Using progressive solidification process and making Cr7C3 type carbide vertical growth against the working face. In the case of not lower the toughness of the parts, Meanwhile
Cr7C3 type face macro hardness and micro hardness also increased.
2. Using multiple micro-alloyed methods to receive dispersion strengthened and progressive hardening and impact crusher wear parts .
3. Using annealing, quenching, tempering heat treatment process to make the blow bars’ surface hardness reaches 58-65HRC.
