HPP 226M

SEVERE ABRASION & IMPACT                                         HARD-FACING

GENERAL CHARACTERISTICS

Deposit of HPP226M is a medium chromium carbide surfacing alloy.  It has excellent combination of abrasion resistance and impact resistance properties.  The weld metal has high toughness and less stress relief check cracks. 

TYPICAL APPLICATIONS: Cone crusher bowls & mantles, hammer mill hammers, grader blades & roll crushers
