High Chrome Cast Iron Wear Parts

Blow Bars

Blow Bars

Blow bars in impact crushers benefit from high-chrome cast iron's superior abrasion resistance. Cr26 provides maximum wear life for hard, abrasive feed materials. Ideal for secondary and tertiary crushing.

Cr26HRC 58-65

Excellent abrasion resistance with M7C3 carbide network; 3-5x longer life than Mn steel in pure abrasive wear; ideal for...

Cr20HRC 55-62

Better toughness than Cr26 with slightly lower abrasion resistance; preferred for impact + abrasive combined conditions ...

Mill Liners

Mill Liners

Mill liners made from high-chrome cast iron provide exceptional wear resistance in grinding applications. Cr26 liners last 2-3x longer than Cr-Mo steel in abrasive ore conditions.

Cr26HRC 58-65

Excellent abrasion resistance with M7C3 carbide network; 3-5x longer life than Mn steel in pure abrasive wear; ideal for...

Cr20HRC 55-62

Better toughness than Cr26 with slightly lower abrasion resistance; preferred for impact + abrasive combined conditions ...

Grinding Balls

Grinding Balls

High-chrome grinding balls provide superior wear resistance and low breakage rates in ball mill grinding. Cr26 balls maintain shape and size consistency for efficient grinding performance.

Cr26HRC 58-65

Excellent abrasion resistance with M7C3 carbide network; 3-5x longer life than Mn steel in pure abrasive wear; ideal for...

Impellers

Impellers

Pump impellers and volute liners in slurry pumping applications. High-chrome cast iron resists both erosion and corrosion in aggressive slurry environments.

Cr26HRC 58-65

Excellent abrasion resistance with M7C3 carbide network; 3-5x longer life than Mn steel in pure abrasive wear; ideal for...

Cr20HRC 55-62

Better toughness than Cr26 with slightly lower abrasion resistance; preferred for impact + abrasive combined conditions ...
