Warranty

Quality guaranteed under standard stone crushing working conditions

Certification

ISO 9001, CE

Standard

ASTM A128, GB/T 5680

Inspection

Hardness test, impact test, abrasion test, metallographic examination, UT nondestructive testing, full dimensional inspection

Application Scope

Fixed jaw plates, movable jaw plates, tooth plates for primary jaw crushers, crushing limestone, granite, basalt, quartz and various hard ores

Delivery Time

10–30 working days, negotiable for large bulk orders

Transport Package

Steel frame reinforced seaworthy wooden case, anti-rust, shockproof and tooth surface scratch protection

Advantages

Excellent work hardening property, dual resistance to heavy impact and abrasive wear, anti-cracking, low deformation, long service life, outstanding cost performance

Typical Chemical Composition (wt%)

Mn13

C 1.0–1.4, Mn 11.0–14.0, Si ≤1.0, S ≤0.05, P ≤0.07

Mn18Cr2

C 0.9–1.3, Mn 17.0–19.0, Cr 1.5–2.5, Si ≤1.0, S ≤0.05, P ≤0.07

Core Material Performance

Original hardness: HB 200–260
Work-hardened surface hardness after impact: HB 450–550
Single-piece high impact toughness, not easy to break under large stone instantaneous impact
Dense austenite microstructure, strong resistance to extrusion abrasion from sharp stone particles

Key Product Features

Unique work hardening characteristic: The tooth surface continuously hardens under stone squeezing impact, forming a wear-resistant layer while the inner layer remains tough to avoid fracture
Dual-proof performance: Balanced heavy impact resistance and particle abrasion resistance, perfectly match jaw crusher intermittent crushing load
Optimized tooth structure design, improves crushing efficiency and reduces material slipping loss
Complete water toughening heat treatment eliminates casting brittleness, effectively prevent tooth plate cracking and block falling
Two grades available: Mn13 for medium-hard stone; Mn18Cr2 for extra-hard abrasive rock with longer service cycle

Main Matching Products

Fixed jaw plates, swing jaw plates, segmented tooth plates, side guard plates for all types of primary jaw crushers.

FAQ

Q: What is the core advantage of manganese steel jaw plates?

A: Hadfield manganese steel gets harder under impact force. It combines tough substrate and wear-resistant surface, solving the conflict between anti-breakage and anti-wear for jaw crushing.

Q: How to choose Mn13 or Mn18Cr2?

A: Mn13 suits limestone, soft ore; Mn18Cr2 with chromium additive is for granite, basalt, lithium ore and highly abrasive hard rock.

Q: Can customize tooth height, plate thickness and mounting holes?

A: Yes, full OEM customization according to crusher model, feeding size and raw material hardness.

Q: Can supply complete inspection certificates?

A: Hardness, metallographic, impact and non-destructive test reports can be provided for factory acceptance.

Our Strengths

Specialized manganese steel casting and water toughening production line for crusher wear parts
Optimized casting mold to strengthen tooth root and reduce fracture risk
Strict raw material composition control to guarantee stable work-hardening performance
Stable mass supply for global quarry, mining and aggregate crushing projects
