Severe impact + continuous abrasion — the specialism of manganese and chrome steel
Crushers and quarry equipment combine the two hardest operating cases together: severe impact from rock and continuous abrasion from sharp material. Here manganese (Hadfield) steel shows its distinction, getting harder the more it is struck — delivered ductile so it absorbs impact without fracture, and its surface work-hardens in service until it resists wear. For abrasive positions without severe impact, high-chrome iron is the more suitable choice.
