WearTuf 400 Abrasion-Resistant Steel Plate: Premium Martensitic Alloy for Extreme Wear Applications.
Ultra-Hard, High-Toughness Wear Solution
WearTuf 400 is a fully martensitic, quenched-and-tempered (Q&T) abrasion-resistant steel plate with an average hardness of 400 HBW (Brinell). Engineered for severe wear environments, it combines exceptional crack resistance (45J impact toughness at -40°C/-40°F) with cold-forming flexibility and weldability. Ideal for mining buckets, crushers, and conveyor systems, it reduces downtime by 50% compared to AR400 steel.

Alloy Design:
- Carbon Equivalents: CEV = C + Mn/6 + (Cr+Mo)/5; CET = C + (Mn+Mo)/10 + Cr/20.
- Boron (0.004%): Enhances hardenability during quenching (JIS G4057).
- Low Sulfur (0.010%): Minimizes hot cracking in high-heat welds (AWS D1.1).
Mechanical Properties
| Yield Strength (Rp0.2) | Tensile Strength (Rm) | Elongation (A5) | Impact Toughness (-40°C) |
|---|---|---|---|
| ≥1,000 MPa | 1,250–1,450 MPa | ≥10% | 45J (EN ISO 148-1) |
Performance Highlights:
- 1,450 MPa Tensile Strength: 20% higher than standard AR400 grades.
- 45J Charpy V-Impact: Maintains ductility in Arctic mining and oil/gas applications.
- Thickness Range: 4–50mm, precision-cut to ±1mm (laser/plasma).
Applications
- Mining: Excavator buckets, rock crusher liners, and trommel screens.
- Transport: Dump truck beds, tipper bodies, and railcar liners.
- Agriculture: Plowshares, harvester blades, and grain chutes.
- Recycling: Shredder hammers, conveyor augers, and waste sorting systems.
Fabrication & Processing
- Cutting: Laser/plasma/oxy-fuel with pre-heating (200°C for >25mm).
- Welding: Compatible with SMAW, GMAW, and FCAW (use low-hydrogen electrodes).
- Bending: Minimum bend radius = 3x plate thickness (cold-formed).
- Machining: Carbide-tipped tools recommended for drilling/milling.
Quality Assurance
- Ultrasonic Testing: EN 10160 Class E1/S1 for zero slag inclusions.
- Hardness Mapping: 3-point depth testing (surface, 1/4 thickness, center).
- Certifications: Mill test reports (EN 10204 3.1), CE/PED compliance.
Industry Innovations
- Lightweight Design: 4mm-thin plates reduce equipment weight by 30%.
- Hybrid Layering: WearTuf 400 cladding on mild steel for cost efficiency.
- Robotic Welding: Pre-qualified for automated MIG welding systems.
Competitive Advantages
- Lifespan: 2x longer than NM400 in abrasive slurry environments.
- Lead Time: 15–25 days (MOQ 10MT).
- Global Stock: EU, USA, and Asia warehouses.
Logistics & Compliance
- Packaging: VCI-coated + edge protectors for Ocean Freight.
- Temperature Warning: Avoid service temperatures >250°C (no post-weld heat treatment).
- Custom Sizes: 900–3,100mm width; 4,000–18,000mm length.
Logical Connectors:
- Comparison: While AR500 offers higher hardness, WearTuf 400 excels in weldability.
- Example: For instance, recycling plants use it for shredder hammers.
- Cause-Effect: Low sulfur (0.010%) reduces porosity in high-heat welds.
