Product Overview & Technical Excellence

MP Mining's Alloy Steel Jaw Plates represent the perfect fusion of advanced metallurgy and precision machining. Specifically engineered for high-impact and highly abrasive environments, our jaw plates ensure consistent performance in gold, copper, and iron ore mines worldwide.

Superior Material Specifications

Mn13Cr2

Cost-effective solution for low to medium hardness material

Mn18Cr2

The industry standard, offering a perfect balance between high impact and high abrasion resistance.

Mn22Cr2

Designed for extremely hard rock (e.g., river pebbles, iron ore) with superior deformation resistance.

TIC Inserts

Optional Titanium Carbide (TIC) columns for double protection in extreme wear conditions.

High-End Manufacturing Process

01.

Water Toughening Treatment

Controlled via microcomputer, our step-heating and high-power water quenching ensure a stable 100% pure austenite structure.

02.

In-house Precision Machining

We machine the back of each jaw plate to ensure it sits perfectly flush with the main frame, preventing bolt loosening and frame damage.

Key Benefits for Your Operation

Work-Hardening Performance

Our plates start at HB200 and rapidly harden toHB500+under crushing impact, providing a hard exterior while maintaining interior toughness to prevent cracking.

100% Fit Guarantee

Compatible withMetso Nordberg C Series (C63–C200)andSandvik CJ Series (CJ408–CJ815).Ready to use without any field grinding.

Optimized Tooth Profiles

Available in Standard, Quarry, Super Grip, and Heavy Duty designs to match your specific rock type and crushing efficiency needs.

Quality Assurance & Traceability

MP Mining is anISO 9001:2015certified manufacturer. Every batch of our alloy steel jaw plates comes with:

Full Technical Dossier

Material reports, dimensional inspection reports, and heat treatment curves.

Non-Destructive Testing

UT (Ultrasonic), MT (Magnetic Particle), and PT (Penetrant Testing) options to guarantee zero internal or surface defects.

Metallographic Validation

Ensures zero network carbide precipitation, the fundamental guarantee of "Hard but Not Brittle" performance.
