Challenging Traditions: How High-Hardness Wear-Resistant Steel Redefines Cost Efficiency in Mining

In quarrying and mining operations, wear-resistant liners for fixed equipment (such as hoppers, crusher hammers, and chute liners) endure constant abrasion from rocks and ores. Traditional AR400 steel plates (approximately 400 HBW) face frequent replacements and high maintenance costs due to rapid wear. Baosteel's AR500 wear-resistant plates, with superior hardness and comprehensive performance, are revolutionizing industry standards through technological innovation.

Mining Equipment

​I. From AR400 to AR500: Quantifiable Cost-Efficiency Leap

Baosteel’s test data reveals that upgrading to AR500 plates ​doubles service life (from 2.4 to 4.8 years) and optimizes total lifecycle costs systemically

  • 50% reduction in procurement costs: Halved material consumption over the equipment’s lifespan.
  • Enhanced processing efficiency: 50% less machining and installation labor, reducing downtime and idle costs.
  • 50% fewer downtime events: Replacement frequency drops from twice to once, minimizing production interruptions.
  • 40% lower daily operational costs: Savings from reduced maintenance, material purchases, and downtime.

​II. Core Technical Advantages of AR500

  1. Uniform Through-Thickness Hardness Unlike conventional wear-resistant steels with hardness degradation, AR500 maintains ​**≥90% hardness uniformity** from surface to core, ensuring long-term protection under extreme abrasion
  2. Outstanding Mechanical Properties
  3. Predictable Machinability Tight thickness tolerance and flatness control (≤0.8 mm/m²) ensure stability during bending and cutting, minimizing secondary processing waste

​III. Sustainability: Cost Savings Meet Environmental Benefits

AR500’s durability extends beyond cost reduction to ecological advantages

  • 50% lower carbon footprint: Reduced steel production, transportation, and processing over the equipment lifecycle.
  • Extended recycling cycles: Fewer replacements cut waste generation.
  • Lightweight design potential: Thinner plates (e.g., 20% weight reduction in dump truck liners) lower fuel consumption and emissions.
