Mn13 High Manganese Wear Resistant Steel, also known as Hadfield Steel, is a high manganese austenitic alloy with excellent work hardening properties under heavy impact or pressure.
Key Features
Work Hardening: Under high stress or impact, the surface hardness increases rapidly from 200 HBW to >500 HBW, forming a wear resistant layer while maintaining core toughness.
Self-Renewing Wear Resistance: As the surface layer wears, continuous hardening occurs, ensuring long-term durability.
Ductility and Machinability: Good weldability and formability are maintained in the pre-hardened state.
Mn13 wear-resistant steel plates are widely used in high-impact environments:
Mining and construction: crusher liners, buckets and conveying systems.
Railways: turnout plates, turnout components.
Energy and heavy machinery: ball mill liners, crusher jaws.
Advanced applications: bulletproof vehicles, maglev train components.
FAQ
Q: Does Mn13 require post-manufacturing heat treatment?
A: No, it is usually used in the water-quenched (solution treated) condition.
Q: Is Mn13 corrosion-resistant?
A: No. Coatings (e.g. galvanizing) are recommended for corrosive environments.
Q: Can Mn13 replace SM490 steel?
A: No. SM490 is a structural steel with unique composition and impact toughness requirements.
