I. Introduction to the High-Manganese Steel Product Series
High-manganese steel is a wear-resistant steel series renowned for its exceptional toughness and strong work-hardening properties, making it particularly suitable for applications involving high-impact and high-stress conditions. Its typical grades include Mn13 (ZGMn13) and a range of modified variants.
Core features:
Characteristics |
Principle |
Numerical Performance |
Work Hardening Property |
Under impact loading, a martensitic phase transformation occurs in the surface layer, causing the hardness to jump from HB200 to over HB500. |
Hardened layer depth: 5-15mm |
Ultra-high toughness |
The fully austenitic microstructure absorbs impact energy, with a tensile strength ≥800 MPa. |
Impact toughness: ≥150 J (retains performance even at -40°C) |
Impact fatigue resistance |
Under cyclic impact, the hardened layer and ductile matrix synergistically resist cracking. |
3 to 5 times higher crack resistance than ordinary steel |
II. Mainstream Grades and Applicable Scenarios
1. Classic Mn13 series (Chinese Standard ZGMn13) composition: C 1.1–1.4%, Mn 11–14%, Si 0.3–0.8%, P/S ≤ 0.05%. Heat treatment: 1050°C water toughening treatment (austenitizing + water quenching).
Applicable components: Jaw crusher jaw plates (for high-impact applications), cone crusher mantle liners, and excavator bucket teeth (requiring complementary surfacing welding for reinforcement).

III. Key Control in Manufacturing Processes
Smelting and Casting
Vacuum deoxidation: Reducing oxygen content to ≤30 ppm (minimizing inclusions)
Low-temperature pouring: 1480–1520°C (to prevent manganese burn-off)
Chill Optimization: Electromagnetic thermal chills for shrinkage compensation, reducing shrinkage porosity by up to 90%.
Surface Enhancement Technology
Explosive Hardening: Pre-hardened surface up to HB350, reducing early wear
Tungsten carbide surfacing: WC cladding applied to tooth tips/edges, extending service life by up to 200%.
The Three Indispensable Applications of High-Manganese Steel
Super-strong Impact: Crusher Feeder with Ore Free-Fall Height > 5m
Multi-directional Stress: Cone Crusher Mantle Wall (3D Compressive Stress)
Ultra-low-temperature environment: -50°C polar mining equipment (austenitic structure remains non-brittle)
High-manganese steel, with its unique property of becoming "harder under impact," remains the material of choice for high-kinetic-energy wear scenarios in industries such as mining, metallurgy, and building materials.
