What is Abrasion-Resistant Steel? Properties, Composition and Applications

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

Carbon is added during the formation of steel plate which considerably increases hardness and toughness, but reduces strength. Hence, the AR plate is employed in conditions where wear and tear and abrasions are the main causes of failure. The AR plate is not perfect for structural construction applications, like support beams in buildings or bridges.

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

Abrasion-Resistant Steel Properties, Composition and Applications

The difference between an abrasion-resistant steel plate and an ordinary steel plate is very important, yet the differences between NM500, NM450, and NM400 are more subtle. In this article, the production of abrasion-resistant steel plate is described and the differences between hardness levels are studied.

NM400 vs. NM450 vs. NM500 — Understanding Abrasion-Resistant Steel

In fabrication and construction, the composition and grade of the steel plate materials used have a tremendous effect on the end product. Abrasion-resistant steel plate is a normal steel plate that possesses a tougher, harder quality that lasts about four times longer when compared to a common high-strength structural steel plate.
