Abrex 400/450/500 represents a range of abrasion-resistant (AR) steel plates developed by Nippon Steel & Sumitomo Metal Corporation (NSSMC). Known for their exceptional wear resistance and mechanical strength, these plates are built to perform in tough environments where components are exposed to continuous friction, impact, and heavy loads. Key Characteristics: Hardness: Abrex 400: 360–440 Brinell Hardness Number (BHN) Abrex 450: 420–480 BHN Abrex 500: 470–530 BHN Superior Wear Resistance: Offers high protection against abrasive damage, making it ideal for applications involving intense wear and tear. Mechanical Performance: High tensile strength and toughness provide excellent structural reliability under harsh working conditions. Weld-Friendly: Can be welded using standard methods, though controlled preheating and cooling are advised to maintain its integrity and prevent heat-affected zone issues. Chemical Composition: Abrex plates are alloyed with a precise combination of: Carbon (C) Manganese (Mn) Silicon (Si) Chromium (Cr) Nickel (Ni) Boron (B) Plus additional trace elements to refine toughness and strength Common Applications: Heavy mining and quarrying equipment Construction vehicles and attachments Agricultural tools and earthmoving parts Railway cars, tippers, and storage bins Wear liners in chutes, hoppers, and conveyors Shot blasting systems and industrial handling machinery Key Advantages: Significantly longer service life in high-abrasion settings Reduced equipment downtime and operational costs Maintains structural strength while minimizing overall weight Reliable performance in both impact and sliding wear scenarios Production Process: Manufactured using a quenching and tempering process, Abrex steel achieves a fine, hardened structure that combines wear resistance with internal toughness, ensuring both surface protection and core strength. Sizes and Availability: Abrex plates are offered in a variety of thicknesses and standard/custom dimensions, adaptable to suit different industry requirements and design specifications.
