1) Abrasion resistant (AR) steel plate is a high-carbon alloy steel plate. This means that AR is harder due to the addition of carbon, and formable and weather resistant due to added alloys.

2) Carbon added during the formation of the steel plate substantially increases toughness and hardness, but reduces strength. Therefore, AR plate is used in situations where abrasions and wear and tear are the main causes of failure. AR plate is not ideal for structural construction uses, like support beams in bridges or buildings.

Common uses for AR plate include conveyors, buckets, dump liners, construction attachments, grates, body armor and ballistic plates (and as targets at shooting ranges).

How the Quenched & Tempered Process Creates AR Plate

Abrasion Resistant (AR) steel plate is typically made in the as-rolled condition. These types/grades of steel plate products have been developed specifically for long service life in harsh conditions. AR products are suitable for a variety of applications in areas such as mining/quarrying, conveyors, material handling and construction, and earthmoving.

3) Designers and plant operators choose AR plate steel when striving to extend the service life of critical components, and reduce the weight of each unit put into service. The benefits of employing wear-resistant plate steel in applications involving impact and/or sliding contact with abrasive material are immense. 

4) Steel plate for use in abrasive conditions is not typical because it is not governed by any ASTM code or spec. Many steel plate manufacturers produce their own brand of abrasion resistant steel and these are usually distinguished by a brand name followed by the hardness of the steel which is measured in Brinell units

5) AR material is produced by quenching and tempering forged steel blocks, or ingots. During this process, the grain structure is changed to increase toughness and encourage formability (or, to be less brittle), and results in through-hardening of the material.
