AR steel or abrasion-resistant steel differs from other types of steel in that it has a higher carbon content, which makes it particularly hard and wear-resistant. Thanks to the addition of special alloys, it remains formable and is weather-resistant. It is therefore particularly suitable for use in civil engineering, mining or agriculture and is used, for example, in excavators, concrete mixers, crushing and screening equipment or in refuse trucks.

A​​​​s a material, wear-resistant steel does not follow standards as structural steel does, for example. Therefore, there is no uniform process for AR steel production, but it is usually heat treated. Ultimately the key feature is its hardness level, which is measured through a Brinell hardness test. The Brinell hardness (HB) for abrasion-resistant steel is between 400 - 600 HB, depending on the product. The higher the HB value, the harder the steel.

There are two recognised processes for producing AR steel. The most commonly used is the Reversing Mill Plate (RMP) process, where the steel is reverse-rolled through a Steckel mill until it reaches the desired thickness. The second process takes place through a wide hot strip mill. Due to the sheer scale of the rolling mill (around 800 m in length), it requires significantly more investment by the steel manufacturer, which is why this process is less widespread. However, it is not only more efficient than RMP, but also produces a steel strip products with better surface quality and greater consistency.
