Product Introduction

JFE EVERHARD EH Series Abrasion-Resistant Steel Plates: Engineered for Extreme Wear Resistance.‌

‌Ultra-Durable Alloy for High-Stress Industrial Applications‌

JFE EVERHARD EH360, EH400, and EH500 abrasion-resistant (AR) steel plates are premium quenched-and-tempered alloys designed to outperform mild steel in harsh environments. With hardness levels up to ‌550 HBW‌ (EH500) and yield strengths exceeding ‌1,200 MPa‌, these plates extend equipment lifespan in mining, cement production, and heavy machinery. Applications include crusher liners, bulldozer blades, and conveyor systems exposed to abrasive ores, gravel, and slag.


‌Key Features & Certifications‌

  • ‌Quenched & Tempered (Q&T)‌: Optimized hardness-depth profile (JIS G3106 / ASTM A514).
  • ‌Boron-Enhanced Toughness‌: Reduces crack propagation risk by 30% in high-impact zones.
  • ‌Custom Coatings‌: Pre-painted options (EP, PE, HDP) for corrosion resistance in wet environments.
  • ‌Global Compliance‌: Meets ISO 683-1, EN 10083, and JFS 6001 standards.

‌Technical Specifications‌

‌Chemical Composition (Max Weight %)‌

Grade C Si Mn P S Cr Ti B
‌EH360‌ 0.20 0.55 1.60 0.030 0.030 0.40 0.005–0.02 0.004
‌EH400‌ 0.25 0.55 1.60 0.030 0.030 0.80 0.005–0.02 0.004
‌EH500‌ 0.35 0.55 1.60 0.030 0.030 0.80 0.005–0.02 0.004

‌Alloy Benefits‌:

  • ‌High Carbon (EH500)‌: 0.35% carbon maximizes surface hardness for rock/ore abrasion.
  • ‌Titanium (Ti)‌: Stabilizes sulfides to prevent hot cracking during welding (AWS D1.1).
  • ‌Low Phosphorus (P)‌: ≤0.030% minimizes brittleness in subzero temperatures.

‌Mechanical Properties‌

Grade Yield Strength (MPa) Tensile Strength (MPa) Hardness (HBW) Impact Toughness (-20°C)
‌EH360‌ ≥800 1,000–1,250 340–400 ≥40 J
‌EH400‌ ≥1,000 1,200–1,450 380–440 ≥35 J
‌EH500‌ ≥1,200 1,450–1,700 470–550 ≥30 J

‌Performance Highlights‌:

  • ‌1,700 MPa Tensile Strength (EH500)‌: 50% stronger than AR400 grades.
  • ‌30 J Impact Toughness‌: Maintains ductility at -20°C (EN 10045).
  • ‌Precision Thickness‌: 6–50 mm with ±0.5 mm tolerance (ISO 9445).

‌Applications‌

  1. ‌Mining‌: Dump truck beds, excavator buckets, and screening plates.
  2. ‌Cement‌: Raw mill liners, clinker crushers, and hopper chutes.
  3. ‌Construction‌: Bulldozer blades, grader edges, and demolition equipment.
  4. ‌Agriculture‌: Plowshares, harvester blades, and tillage tools.

‌Processing & Customization‌

  • ‌Precision Cutting‌: Laser/plasma cutting with ±1 mm tolerance (ISO 9013).
  • ‌Heat Treatment‌: Normalizing (N) or Q&T to balance hardness and weldability.
  • ‌Coating Options‌:
    • ‌Epoxy (EP)‌: Chemical resistance in acidic/alkaline environments.
    • ‌Polyethylene (PE)‌: UV protection for outdoor storage.
    • ‌PVDF‌: Extreme weather durability (20+ years).

‌Industry Innovations‌

  • ‌Hybrid Layering‌: EH500 cladding on mild steel for cost-sensitive projects.
  • ‌3D Profiling‌: CNC-formed curves for crusher jaw plates and shredder rotors.
  • ‌Eco-Friendly Quenching‌: Low-emission heat treatment reduces carbon footprint.

‌Competitive Advantages‌

  • ‌Lifespan‌: 3x longer than AR450 steel in slurry pipelines.
  • ‌Weldability‌: Pre-heated to 150°C for crack-free joints (JIS Z 3701).
  • ‌Lead Time‌: 15–30 days ().

‌Quality Assurance & Logistics‌

  • ‌Mandatory Testing‌: Ultrasonic flaw detection, hardness mapping (3-point rule).
  • ‌Packaging‌: VCI-coated anti-rust paper + wooden crates for.
  • ‌Certifications‌: Mill test reports (EN 10204 3.1), JIS certification.
