Product Overview (Engineering + Procurement Version)
NM400 Wear Resistant Steel Plate is a quench and tempered high-strength abrasion resistant steel plate with a nominal hardness of approximately 400 HBW.
It is specifically designed for high-wear, high-impact industrial environments, where standard carbon steel fails due to rapid surface wear.
By significantly improving wear resistance and service life, NM400 helps industrial users to:
• Reduce equipment downtime
• Extend component lifespan
• Lower maintenance cost
• Improve operational efficiency
Key Advantages of NM400 Wear Resistant Steel Plate
Extreme Wear Resistance
Service life is typically 3–6 times longer than conventional structural steel.
High Mechanical Strength
• Yield strength: ≥1000 MPa
• Tensile strength: 1100–1250 MPa
Excellent Impact Performance
Suitable for high-impact applications such as excavation and crushing systems.
Controlled Fabrication Performance
• Cutting: Laser / plasma / flame
• Welding: Low hydrogen process recommended
• Bending: Possible under controlled radius
Lifecycle Cost Reduction
Significantly reduces:
• Replacement frequency
• Maintenance shutdown
• Equipment wear cost

Application
NM400 is mainly used in wear-critical equipment components:
Mining Equipment
• Excavator bucket liners
• Dump truck body liners
• Crusher wear plates
• Hopper & chute liners
Cement & Aggregate Plants
• Cement mill liners
• Conveyor wear plates
• Material transfer chutes
Heavy Machinery
• Bulldozer blades
• Loader buckets
• Drilling rig wear components
Bulk Handling Systems
• Port hopper liners
• Ship unloading systems
• Conveyor impact zones
Processing & Fabrication Guidelines
Cutting: CNC laser / plasma recommended
Welding: Preheating recommended for thick plates
Drilling: Carbide tools required
Bending: Controlled radius required due to hardness
Quality Control
Every NM400 plate undergoes rigorous testing prior to dispatch to eliminate any quality risks for international buyers:
Chemical Verification: Spectrometer analysis for precise heat chemistry.
Hardness Testing: Brinell hardness mapped across multiple surface points.
Ultrasonic Testing (UT): Conducted in accordance with ASTM/EN standards to detect internal defects.
Dimensional Integrity: Visual and physical tolerance checks (flatness, thickness, width).
Mill Test Certificate (MTC): EN 10204 3.1 or 3.2 certificate provided with every single batch.
Third-Party Inspection: Fully supports and welcomes inspections by SGS, Bureau Veritas (BV), or TÜV.
