AR400 Abrasion Resistant Steel Plate
AR400 steel plate is a high-strength abrasion resistant steel plate designed for applications where severe wear conditions exist. Also known as AR400 wear plate or AR steel, it provides excellent resistance to sliding abrasion while maintaining good toughness and structural strength.
AR400 wear resistant steel is widely used in industries such as mining, quarrying, construction, cement production, and bulk material handling. Equipment operating in these environments is constantly exposed to abrasive materials such as ore, sand, gravel, and slag. Under these conditions, standard structural steels wear out quickly, resulting in higher maintenance costs and frequent equipment replacement.
Compared with conventional structural steel, AR400 abrasion resistant steel plate offers significantly improved wear life while maintaining good weldability, formability, and machinability. This makes it an ideal material for manufacturing wear-prone components such as dump truck bodies, excavator buckets, crushers, hoppers, chutes, and conveyor liners.
