Product Introduction

‌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.


‌Certifications & Key Advantages‌

  • ‌EN 10029 Compliance‌: Exceeds flatness and dimensional tolerances for precision fabrication.
  • ‌EN 10163-2 Class A Surface Finish‌: Shot-blasted + low-zinc silicate primer for corrosion protection.
  • ‌ISO 6506-1 Hardness Guarantee‌: 370–430 HBW surface hardness, 95% center hardness retention in plates >20mm.
  • ‌Global Standards‌: Compliant with ASTM A514, EN 10025, and ISO 4957.

‌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

  1. ‌Mining‌: Excavator buckets, rock crusher liners, and trommel screens.
  2. ‌Transport‌: Dump truck beds, tipper bodies, and railcar liners.
  3. ‌Agriculture‌: Plowshares, harvester blades, and grain chutes.
  4. ‌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 ().
  • ‌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.
