QUAD 400 / 450 / 500 (High-Performance Abrasion-Resistant Steel) QUAD 400/450/500 plates are engineered for use in severely abrasive conditions, offering an optimal combination of hardness, impact strength, and formability. These plates are designed to deliver long-lasting performance in challenging environments such as mining, material handling, and construction. With consistent surface hardness and deep through-hardening, QUAD plates ensure reduced wear, longer component life, and low maintenance cycles. Hardness Levels: QUAD 400: 360–440 BHN QUAD 450: 420–480 BHN QUAD 500: 470–530 BHN Key Features: High wear resistance in abrasive and high-impact environments Enhanced structural strength for use in load-bearing components Good cold bending and cutting capabilities High surface uniformity for better fabrication outcomes Common Applications: Mining and quarrying tools Construction and earthmoving machinery (e.g., blade liners, side cutters) Material transport systems (e.g., conveyors, transfer points) Shot blasting equipment and recycling systems
