BHN 550 and 600 Plates represent the pinnacle of abrasion resistance in the quenched and tempered steel category. Engineered for environments where mechanical wear is extreme, these plates offer a level of hardness that effectively bridges the gap between traditional wear plates and expensive hard-faced materials or white iron castings. With a Brinell hardness range of 525 to 640 HBW, BHN 550 and 600 are specifically designed to combat intense sliding abrasion from hard minerals, glass, and metal scrap, ensuring that equipment remains operational in the most hostile industrial conditions.

The primary advantage of utilizing Extreme Wear Resistant AR Plates is the significant extension of maintenance intervals. By deploying BHN 550/600 in high-velocity friction zones, operators can achieve a service life several times longer than that of AR 400 or 450 grades. While these grades prioritize maximum hardness, they are formulated with advanced metallurgical controls to maintain sufficient structural integrity for heavy-duty fabrication. They are the definitive choice for recycling shredders, hammer mills, concrete mixer liners, glass handling equipment, and mineral chutes where the cost of downtime far exceeds the investment in premium wear protection.



BHN 550/600 Plates Features

  • » Extreme Abrasion Shield: Engineered for environments where sliding wear is the primary concern, offering a hardness level that effectively resists penetration from the sharpest minerals and metal scrap.
  • » Maximum Service Life: Provides the longest possible replacement intervals for wear parts, often outlasting standard AR 400 plates by a factor of three or more in high-friction zones.
  • » Cost-Effective Alternative: Acts as a high-performance substitute for expensive hard-facing overlays or specialized manganese castings, reducing both material costs and fabrication complexity.
  • » Through-Hardened Consistency: Advanced quenching technology ensures that the hardness is not just a surface coating but is maintained consistently throughout the entire thickness of the plate.
  • » Optimized Chemical Purity: Formulated with a specific balance of Carbon, Chromium, and Nickel to achieve extreme hardness while retaining enough structural stability to prevent shattering under stress.
  • » Precision Machining Potential: Despite its extreme hardness, the material can be processed with specialized carbide tooling, allowing for the creation of precise liner shapes and bolt-hole configurations.
  • » Low Maintenance Downtime: By significantly reducing the wear rate, these plates minimize the frequency of machine shutdowns for liner replacements, maximizing overall plant productivity.
  • » Superior Flatness & Surface: Delivered with high dimensional accuracy and a clean surface finish, facilitating efficient automated cutting and ensuring a perfect fit during equipment assembly.
