What is Abrasion Resistant Steel?
First, in order to understand what abrasion resistant steel is, it’s important to break through the nomenclature in order to dissect the meaning behind terms like AR400 or AR500. The AR at the beginning of each grade is an abbreviation for “abrasion resistant”. Occasionally, when people see the code AR used in a steel grade, the natural reaction it to assume it could be shorthand for armor plate, however, this is not the case.
While other steel grades are traditionally classified based on their tensile strength, abrasion resistant steels are graded using a method known as the Brinell hardness test. This hardness is then represented as the set of numbers, following AR, in the grade designation. Abrasion resistant steel plate is a high-carbon steel plate that is typically alloyed with a number of different elements such as carbon and boron. This type of steel is usually created using a quenching and tempering process, which increases the hardness of the steel and creates a unique grain structure.
In other words, if you were to order plate that met AR400, you would be able to tell from that designation that you will be getting high-carbon, heat-treated product that creates an abrasion-resistant surface, as well as a hardness around 400 (typically 360-444 BHN).
Properties of AR steel vary depending on the grade. The lower the grade, such as AR400, the more formable the steel is. The higher the grade, like AR500, the harder the steel is. AR450 is right in the middle, denoting a “sweet spot” between hardness and formability. You can view more information about each grade of steel using the buckets below.
What are the Benefits?
The most important benefit of any AR steel is in its durability against scuffing, scratching, and wearing. All AR is resistant to some degree of impact as well. AR steel grades are already being used worldwide for construction purposes. You can find it in the buckets of heavy earth moving excavators and lining the beds of dump trucks.
Abrasion Resistant Steels are useful in any application in which abrasion and impact resistance are crucial. Some common industries include:
- Material Handling
But why stop there? We happen to believe the steel industry and manufacturing as a whole have not yet begun to - pardon the pun – scratch the surface on the full capabilities of these grades. Because of its wear resistant properties, this particular type of steel can last longer in high-stress situations. Additionally, it can potentially reduce the down time you may suffer when components fail and must be replaced. To this note, it can improve the longevity of your machinery and maximize production time.
