View Liner Options >Austenitic Manganese Steel, widely designated as Hadfield steel (originating from Sir Robert Hadfield's pioneering metallurgical discoveries in 1882), represents a unique material category in heavy mechanical and mining operations. Featuring typical chemical formulations comprising 11% to 14% Manganese (Mn) and 1.0% to 1.4% Carbon (C), this alloy is designed specifically for environments where extreme compressive stress, severe mechanical shock, and impact are present.
The primary differentiator of manganese wear plates from alternative wear-resistant steels (such as classic quenched and tempered martensitic steels) is their innate strain-hardening (work-hardening) mechanism. In its delivery state, manganese steel exists in a fully austenitic phase, which is relatively soft, tough, and ductile, measuring approximately 200 to 220 HBW. However, upon exposure to continuous mechanical impact or heavy compressive stresses, the surface layer undergoes rapid plastic deformation. This deformation changes the crystal lattice structure, producing deformation twinning and transforming the soft austenite phase into high-hardness martensite.
This localized transformation elevates the surface layer hardness to upwards of 500 to 600 HBW while leaving the underlying substrate structure soft, tough, and highly ductile. As the hardened outer crust is gradually worn away by operating media, the freshly exposed sub-surface layer work-hardens dynamically. This self-renewing surface prevents brittle fractures under high-impact conditions, making manganese wear plates highly reliable for extreme heavy-duty environments.
Choosing between Austenitic Manganese Wear Plates and Bimetallic Chromium Carbide Overlay (CCO) plates is a critical decision in industrial application design. Both materials are engineered for wear resistance, but they serve distinct operational conditions. The table below illustrates the mechanical profiles and application suitability of these two industry-leading solutions:
| Performance Metric | Austenitic Manganese Wear Plates (e.g., Mn13 / Hadfield) | Chromium Carbide Overlay (CCO) Plates (e.g., RX-wp 7600) |
|---|---|---|
| Primary Wear Mode | Heavy impact, crushing, high-stress pounding | Extreme sliding abrasion, fine-particle scraping |
| Initial Base Hardness | 200 – 220 HBW (highly ductile, ductile-to-brittle resistant) | 55 – 62 HRC (approx. 570 - 700 HBW) throughout overlay |
| Hardening Profile | Dynamic work-hardening under impact up to 550+ HBW | Static high hardness; does not rely on impact to perform |
| Impact Resistance | Outstanding; will not fracture under extreme pounding | Moderate; subject to surface stress relief checking/chipping |
| Typical Chemical Profile | 11-14% Mn, 1.0-1.4% C, optional Cr additions (e.g., Mn13Cr2) | 4.0-5.5% C, 25-35% Cr, micro-alloys (Nb, V, W, B) |
| Fabrication Methods | Primarily casting or hot-rolled plate, specialized welding | Clad welding on mild/low alloy backing plate structure |

Read More >Manganese steel (typically 11-14% Mn) is designed to resist heavy impact and high-stress crushing, work-hardening from 200 HBW up to over 550 HBW during service. In contrast, Chromium Carbide Overlay (CCO) plates provide high, static initial hardness (58-62 HRC) and are designed to resist severe sliding abrasion. CCO plates perform best in high-wear, low-impact environments, while manganese plates are suited for high-impact applications.
Manganese liners are widely used in heavy mining (jaw, cone, and gyratory crusher liners), cement manufacturing (clinker chutes and primary feed hoppers), steel production, aggregate quarrying, and recycling industries. Any application where large rocks, ore, or dense materials strike metal surfaces with high energy is suitable for manganese wear liners.
Manganese steel can be cut using plasma arc or laser systems. Oxy-fuel cutting is possible but requires care to avoid overheating, which can cause carbide precipitation and embrittlement. Welding must be performed using low-heat inputs and specialized high-manganese electrodes or flux-cored wires (such as Runxing's hardfacing wire) to maintain the tough austenitic phase and prevent crack propagation.
Our manufacturing processes follow ISO 9001 quality systems. Raw materials and alloys are tested for chemical composition, microstructure, and hardness. Our hardfacing weld deposits are designed to meet relevant international standards, including DIN 8555, and our close partnership with VAUTID Germany helps maintain consistent quality across our premium product lines.
