Engineered for extreme mining environments, our 10mm NM400 wear resistant steel plate delivers unmatched durability against abrasive materials. Specifically developed for heavy-duty mining equipment applications, this high-performance steel significantly extends component service life while reducing maintenance downtime. The optimized hardness-to-toughness balance ensures reliable performance in impact-intensive operations like ore processing and material handling. With proven resistance to deformation under continuous stress, it provides a cost-effective solution for operations seeking to maximize equipment productivity.
Manufactured through precision-controlled quenching and tempering processes, each plate undergoes rigorous quality verification to maintain consistent mechanical properties across the entire surface. The metallurgical structure features fine-grained martensite that effectively distributes impact energy while maintaining surface integrity under repeated abrasion.
Key technical advantages include: superior wear resistance that outperforms standard carbon steels by 4-6x; excellent weldability allowing easy integration into existing structures; and consistent through-thickness properties ensuring uniform performance even after machining.
| Property | Value | Testing Standard |
|---|---|---|
| Yield Strength | ≥1000 MPa | ASTM E8 |
| Elongation at Break | ≥12% | ASTM E8 |
| Flatness Tolerance | ≤3mm/m | EN 10029 |
| Density | 7.85 g/cm³ | ISO 1183 |
The plate's exceptional performance stems from its optimized chemical composition featuring carbon (0.20-0.25%), manganese (1.60% max), chromium (1.40% max), and boron additions that create hard carbides within the steel matrix. This microstructure effectively resists material gouging and surface deformation when exposed to abrasive minerals like iron ore, copper slag, or granite aggregates.
Common mining applications include:
- Dump truck body liners - withstands impact from rock loading/unloading
- Crusher jaw plates - maintains sharp edges under constant abrasion
- Screening mesh supports - resists vibration-induced wear
- Conveyor system components - reduces material adherence and buildup
- Loader bucket liners - protects against rock penetration and scraping
Processing flexibility allows customization to specific operational needs. Options include:
- Plasma/oxy-fuel cutting to complex shapes
- Drilling and tapping for bolt-on installation
- Shot blasting for improved paint adhesion
- Hardfacing overlay for extreme wear zones
Transform your mining equipment maintenance strategy with our engineered wear solution. By significantly extending component replacement intervals—typically by 300-400% compared to mild steel—this plate delivers measurable cost savings through reduced part inventories and maintenance labor. Available in standard 1500×3000mm and 2000×6000mm dimensions, with custom cutting services available upon request.

Frequently Asked Questions
Q: What distinguishes NM400 from other wear-resistant steels?
A: NM400 offers a balanced combination of hardness (400 HB minimum) and impact toughness, making it suitable for applications involving both abrasion and moderate impact loads. The quenched and tempered microstructure provides better crack resistance than higher hardness steels.
Q: Can this plate be welded without preheating?
A: Preheating to 150-200°C is recommended for thicknesses above 8mm to prevent hydrogen cracking. Use low-hydrogen electrodes and maintain interpass temperatures below 250°C for optimal results.
Q: What surface treatments are available?
A: Standard supply is as-rolled surface. Optional treatments include shot blasting (SA 2.5 standard) or primer coating for corrosion protection during storage and transport.
Q: How does thickness affect wear life?
A: The 10mm thickness provides optimal balance between weight and wear resistance for most mining applications. Thinner plates wear through faster, while thicker plates add unnecessary weight without proportional wear life increase.
Q: What quality documentation is provided?
A: Each shipment includes material test reports showing actual chemical composition and mechanical properties. Additional certifications like EN 10204 3.1 are available upon request.
Q: Can I get custom hole patterns or shapes?
A: Yes, we offer precision CNC cutting services to produce ready-to-install components with bolt holes, cutouts, or complex contours based on your technical drawings.
