Product Introduction

‌XAR Abrasion-Resistant Steel Plate: Engineered for Extreme Wear Resistance.‌

‌Ultra-Durable Alloy for Harsh Industrial Applications‌

XAR abrasion-resistant steel plates are heat-treated, high-carbon alloys designed to withstand severe wear, impact, and abrasive forces in mining, cement production, and heavy machinery. With hardness levels up to ‌600 HB‌ (Brinell) and yield strengths exceeding ‌1,500 MPa‌, these plates minimize equipment downtime in high-stress environments like crusher liners, bulldozer blades, and conveyor systems.


‌Key Features & Certifications‌

  • ‌Quenched & Tempered (Q&T) Treatment‌: Achieves uniform hardness (EN 10083-3).
  • ‌Boron-Enhanced Toughness‌: Reduces crack propagation by 35% (ASTM A514).
  • ‌Customizable Thickness‌: 3–100 mm (precision-cut via laser/plasma).
  • ‌Global Standards‌: Complies with ISO 683-18, DIN 17022, and AS 3679.1.

‌Alloy Benefits‌:

  • ‌High Carbon (0.40% in XAR600)‌: Maximizes surface hardness for rock/ore abrasion.
  • ‌Chromium (1.5% in XAR600)‌: Enhances corrosion resistance in wet mining environments.
  • ‌Boron (0.005%)‌: Improves hardenability during quenching (JIS G4053).

‌Mechanical Properties‌

Grade Tensile Strength (MPa) Yield Strength (MPa) Elongation (%) Hardness (HBW)
XAR400 1,300 1,150 ≥12 360–440
XAR450 1,350 1,200 ≥10 410–490
XAR500 1,600 1,500 ≥9 450–530
XAR550 1,750 1,650 ≥8 500–580
XAR600 1,800 1,700 ≥7 ≥550

‌Performance Highlights‌:

  • ‌1,800 MPa Tensile Strength (XAR600)‌: 30% stronger than AR400 grades.
  • ‌12% Elongation (XAR400)‌: Balances ductility with wear resistance.
  • ‌-40°C Impact Toughness‌: Optional Charpy V-testing for Arctic applications.

‌Applications‌

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

‌Advanced Processing & Customization‌

  • ‌Precision Cutting‌: Laser/plasma cutting with ±1mm tolerance (ISO 9013).
  • ‌Stress-Relief Annealing‌: Optional for welded components (AMS 2759).
  • ‌Surface Finishing‌: Shot blasting to ‌Sa2.5‌ (ISO 8501) for coating adhesion.

‌Industry Innovations‌

  • ‌Eco-Friendly Quenching‌: Low-emission heat treatment reduces carbon footprint.
  • ‌3D Profiling‌: CNC-formed curves for crusher jaw plates and shredder rotors.
  • ‌Hybrid Layering‌: XAR600 cladding on mild steel for cost-sensitive projects.

‌Competitive Advantages‌

  • ‌Lifespan‌: 3x longer than manganese steel in slurry pipelines.
  • ‌Weldability‌: Pre-heated to 150°C for crack-free joints (AWS D1.1).
  • ‌Lead Time‌: 15–30 days (MOQ 10MT).

‌Quality Assurance & Logistics‌

  • ‌Mandatory Testing‌: Hardness mapping (3-point rule), PMI, ultrasonic inspection.
  • ‌Packaging‌: VCI-coated anti-rust paper + wooden crates for.
  • ‌Certifications‌: Mill test reports (EN 10204 3.1), ISO 9001:2015.
