Blow Bar, Impact Plate

– Impact Crusher Wear Parts

The main wearing parts of Impact Crusher are blow bars and impact plates, with special heat-treatment, the hardness of our blow bar can reach to HRC58~HRC63. The product mainly uses high manganese steel material, for example Mn14Cr2, Mn18Cr2, Mn22Cr2 and so on.

Willing’s blow bars and impact plates are widely used on mining, construction, chemical, cement and metallurgical industry. Our impact parts have a service life 50~100% longer than those made of traditional high chromium iron.
