What is ABREX 500
ABREX 500 is part of Nippon Steel’s ABREX™ series, engineered for high wear resistance (approximately 500 HBW hardness) champaksteel.com+11nipponsteel.com+11csecplates.com+11.
Optimized for applications involving severe abrasion and impact, while retaining excellent weldability and formability nipponsteel.com+3prosaicsteel.com+3wixsteel.com+3.
Key Properties & Specs
Hardness: Around 500 HBW (~515 BHN typical) textronsteelalloys.com+1wearplates.co.in+1.
Thickness Range: Offered from ~4.5 mm up to 100 mm, depending on grade and manufacturer conqueststeelalloys.in+2textronsteelalloys.com+2multimetalsindia.com+2.
Chemical Composition: Includes carbon (≤ 0.35 %), manganese, chromium, nickel, molybdenum, and trace boron to balance hardness and toughness prosaicsteel.com+1dl.asminternational.org+1.
Mechanical Strength: Tensile strength in the range of 1,200–1,600 N/mm², with high impact resistance nipponsteel.com+5wixsteel.com+5nipponsteel.com+5.
Formability and Weldability: Good bending characteristics; welding requires appropriate preheating to avoid cracking tronixalloys.com+12csecplates.com+12multimetalsindia.com+12.
Advantages
Superior Wear Resistance: 3–5× more abrasion-resistant than mild steel – prolongs service life of equipment prosaicsteel.com+4nipponsteel.com+4textronsteelalloys.com+4.
Lightweight Design: Enables lighter structural components compared to using thicker mild steel, leading to economic gains .
Versatile Fabrication: Can be cut, welded, bent, and machined using standard workshop techniques conqueststeelalloys.in.
Typical Applications
Widely used in high-wear, impact-prone environments, including:
Mining & quarrying: dump truck liners, crushers, chutes, screens conqueststeelalloys.in+5prosaicsteel.com+5champaksteel.com+5
Construction & earthmoving equipment: buckets, blades, hoppers, conveyor parts prosaicsteel.com
Bulk-material handling: hoppers, scrapers, wear plates tronixalloys.com+4champaksteel.com+4prosaicsteel.com+4
Handling & Fabrication Tips
Use controlled preheating (often around 75–175 °C depending on plate thickness) to prevent weld cracking csecplates.com+2multimetalsindia.com+2dl.asminternational.org+2.
Adhere to welding guidelines—low impurity levels in ABREX promote good weld quality, but proper technique is essential multimetalsindia.com+2dl.asminternational.org+2nipponsteel.com+2.
Monitor for micro-cracks during forming or bending due to higher hardness and reduced elongation .
