Crusher Parts Material Specifications

Standard high manganese steel with 13% Mn and 2% Cr. Initial hardness HB 200–250, work-hardens to HB 500+ under impact. Cost-effective for moderate impact and abrasive conditions.

Upgraded high manganese steel, 18% Mn + 2% Cr. Greater work-hardening capacity for high-impact, high-abrasion conditions. 20–30% longer service life than Mn13Cr2.

Ti micro-alloyed Mn18Cr2 — Ti refines grain structure, suppresses carbide precipitation, and enhances toughness and work-hardening rate. For severe impact conditions.

Super-high manganese steel, 22% Mn + 2% Cr. Maximum work-hardening under extreme impact. Ideal for large gyratory crusher primary liners.

Martensitic high chromium cast iron, 26% Cr with Cr7C3 carbides in martensitic matrix. Extreme abrasion resistance for high-abrasion, low-impact conditions.

Mo-alloyed Cr26 — Mo refines carbides and strengthens matrix for improved impact toughness and wear resistance balance.

Medium-carbon alloy structural steel. Q&T treated for excellent combined mechanical properties: high strength, good toughness and fatigue resistance. Preferred for forged main and eccentric shafts.

SSAB wear plate with Brinell hardness HB 450–500. Excellent wear resistance and weldability. Used for feed plates, distribution plates and moderate-wear liners.

Tungsten carbide inserts, hardness HRA 85–90, 5–10× the wear life of high chrome iron. First choice for VSI rotor tips under extreme wear conditions.

Lead bronze bearing alloy with excellent anti-friction and load-carrying capacity. Used for cone crusher eccentric and main shaft bushings for smooth operation.
