AR400 / AR450 / AR500 Plate

Characteristics

AR400, AR450 and AR500 plate are abrasion resistant (AR) quenched and tempered alloy steels. This grade of alloy steel exhibits high abrasion resistance and hardness. The addition of carbon and manganese coupled with quenching and tempering increase the hardness of the steel and create a durable, impact-resistant surface. However, as hardness increases, formability and the ability to easily machine and weld the alloy decrease. Special machining processes are needed to prevent work hardening and chipping during manufacturing.

Applications

AR400, AR450 and AR500 plate are used in applications where abrasive materials such as grains, coal, ore, cement, gravel, light aggregate, and earth are being handled. It is a common material for conveyors, chutes, linings, hoppers and handling equipment in the materials handling and mining industries.

Abrasion resistant steels are not intended for structural applications. These steels should not be used for structural or main load-bearing members because of the possibility that brittle fracture may occur in these high hardness steels at the high stress levels encountered in such applications.
