Crusher Jaw Plates

Our jaw plates undergo rigorous metallurgical processes to deliver exceptional wear resistance, impact strength, and service life, significantly reducing downtime and operational costs for cone crushers, jaw crushers, and hammer crushers.

Material Technology & Grade Selection

1、High-Manganese Steel Jaw Plates (Mn13, Mn18)

Our Mn-series jaw plates feature 11-18% manganese content that develops extreme surface hardness through work hardening during operation:

Mn13: Standard grade for general crushing applications

Initial hardness: 200-250 HB

Work-hardened hardness: 450-550 HB

Excellent impact resistance

Best for medium abrasive materials

Mn18: Premium grade for severe conditions

Initial hardness: 220-270 HB

Work-hardened hardness: 500-600 HB

Enhanced wear resistance

Ideal for highly abrasive granite/basalt

Key Advantages:

✓ Self-hardening during operation

✓ Outstanding impact absorption

✓ Good weldability for repairs

✓ Cost-effective for most applications

2、High-Chromium Cast Iron Jaw Plates (Cr26, Cr28)

Our Cr-series offers superior abrasion resistance through 26-28% chromium content:

Cr26: Standard chromium alloy

Hardness: 58-62 HRC

Microstructure: M7C3 carbides

Best for highly abrasive materials

Cr28: Premium chromium alloy

Hardness: 60-64 HRC

Enhanced carbide distribution

Superior corrosion resistance

Key Advantages:

✓ Exceptional abrasion resistance

✓ Consistent hardness throughout service life

✓ Excellent corrosion resistance

✓ Perfect for silica-rich materials

3、Bimetal Composite Jaw Plates

Our innovative bimetal technology combines the best properties of both materials:

Wear Surface: High-chromium cast iron (60-64 HRC)

Base Structure: Tough manganese steel (200-250 HB)

Metallurgical Bonding: Vacuum casting process

Key Advantages:

✓ Extreme surface hardness + tough core

✓ 2-3x longer lifespan than standard plates

✓ Reduced risk of catastrophic failure

✓ Optimal for mixed material processing
