Wear-resistant steel plate is a type of high-strength steel specifically designed to withstand severe abrasive wear in harsh working environments. These plates are alloyed with elements such as chromium, manganese, and nickel to enhance hardness, toughness, and impact resistance while maintaining good weldability and formability.

It is widely used in industries such as mining, construction, cement, earthmoving, and bulk material handling—especially in equipment like buckets, crushers, hoppers, dump truck bodies, and conveyors.

Common grades include:
China: NM360, NM400, NM450, NM500 (GB/T 24186)
Japan: JFE-EH400, JFE-EH500 (JFE Steel)
USA/General: AR400, AR450, AR500 (Abrasion Resistant grades by various mills)

These plates typically feature a Brinell hardness (HBW) in the range of 360–600, offering exceptional wear resistance with varying levels of toughness and strength depending on the application.
