Quick Material Selection Guide
| Your Application | Recommended Grade | Reason |
|---|---|---|
| Standard-duty, medium-hard ore, crusher 42-65 to 50-65 | Mn13Cr2 | Cost-effective baseline; excellent work-hardening in moderate impact; standard for most mid-size gyratory crushers |
| Hard abrasive ore (granite / quartzite), crusher 54-75 to 60-89 | Mn18Cr2 | Higher Mn content delivers faster and deeper work-hardening; longer life in continuous heavy-impact crushing |
| Ultra-hard ore, high throughput, crusher 60-110 and above | Mn22Cr2 | Maximum Mn for extreme work-hardening depth; resists plastic deformation in the heaviest gyratory applications |
| Very large gyratory (60-89 to 63-114), combined wear + severe impact | ZG-Mn13CrMo | Mo addition ensures through-hardening in very thick sections (>300mm); prevents internal soft spots in massive castings |
| High-abrasion ore where lower mantle wears 3x faster than upper | Bimetal-B (Cr26 + Mn18Core) | Hard wear face on high-wear zone + tough core prevents fracture; 2.5-3.5x life with acceptable cost premium |

Frequently Asked Questions
Quick answers to common questions about our crusher wear parts
We offer four material families tailored to different working conditions:
| Material Series | Grades | Hardness | Best For |
|---|---|---|---|
| High Manganese Steel | Mn13, Mn13Cr2, Mn18Cr2 | HB 200-260 (work-hardens to HB 400-600) | Medium to high impact crushing |
| High Chromium Cast Iron | Cr20, Cr26, Cr15Mo3 | HRC 58-63 | Low impact, high abrasion; fine crushing, sand making |
| Bi-Metallic Composite | Bimetal-A / B / C | HRC 58-68 (working layer) | Combined impact + abrasion; maximum service life |
| Alloy Steel | ZG-Mn13CrMo, Martensitic | HB 300-500 | Balanced toughness and wear resistance |
