NM400 Steel Plate — High Hardness Wear Protection for Extreme Abrasion Environments
When equipment operates under constant impact, sliding friction, and heavy abrasion, standard structural steel fails quickly.
NM400 steel plate is engineered specifically for wear resistance and extended service life, making it a preferred material in mining, quarrying, cement plants, and heavy machinery industries.
✔ High hardness wear-resistant steel
✔ Designed for extreme abrasion environments
✔ Excellent balance of toughness and hardness
✔ Widely used as Hardox-equivalent wear plate in industrial applications
As a global NM400 steel plate supplier and exporter, we provide stable stock, custom cutting, and fast international delivery for industrial procurement projects.

NM400 Chemical Composition
The NM400 steel chemical composition is designed to achieve high hardness with controlled weldability.
- Carbon (C): 0.18% – 0.30%
- Silicon (Si): 0.20% – 0.70%
- Manganese (Mn): 0.90% – 1.60%
- Chromium (Cr): 0.40% – 1.20%
- Nickel (Ni): ≤ 1.00%
- Molybdenum (Mo): ≤ 0.50%
- Boron (B): trace controlled
This composition ensures a hardened microstructure suitable for severe abrasion conditions.
NM400 Mechanical Properties
The NM400 wear resistant steel performance is defined primarily by hardness and wear resistance rather than traditional yield strength.
| Property | Value |
|---|---|
| Hardness | 360 – 440 HBW |
| Yield Strength | Approx. ≥ 900 MPa (reference level) |
| Tensile Strength | 1000 – 1250 MPa |
| Elongation | ≥ 10% |
| Impact Toughness | Good (varies by thickness and condition) |
This combination provides long service life in high-wear mechanical systems.
NM400 Steel Plate Applications
The NM400 wear resistant steel plate is widely used in industries with extreme abrasion and impact loads:
- Mining machinery liners and buckets
- Excavator wear parts and shovel plates
- Cement plant liners and chutes
- Crusher components and hoppers
- Dump truck bodies and liners
- Coal handling and material transfer systems
- Earthmoving and construction equipment
It significantly reduces downtime and maintenance costs in heavy industry operations.
