Quick Selection Guide
| Your Requirement | Recommended Spec | Reason |
|---|---|---|
| Standard cheek plate for general quarry duty, C80-C125 | Mn13Cr2 Cheek Plate | Best cost-performance; adequate work-hardening for typical side-wall abrasive wear |
| Cheek plate for hard abrasive rock, C125-C200 | Mn18Cr2 Cheek Plate | Deeper hardening for extended service life; reduces replacement frequency in heavy-duty operation |
| Standard toggle plate replacement, C80-C110 | HT200 Gray Cast Iron | Predictable brittle fracture at OEM-specified break load; industry standard for all mid-size jaw crushers |
| Heavy-duty toggle plate, C125-C200 | HT250 Gray Cast Iron | Higher tensile strength for larger crushers; maintains brittle fracture characteristic at higher loads |
| Replacement toggle seat / wedge set | QT500-7 Ductile Iron | Toggle seat must not fracture — ductile iron provides the necessary strength and wear resistance |
| Emergency steel toggle for quick re-start | ZG30Mn — TEMPORARY ONLY | Steel toggle keeps crusher running while OEM toggle is on order. Replace with HT grade at earliest shutdown |

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 |
