AR500 - Hardness 460-544 brinell

What is AR500 Steel?

Much like AR450 and AR400, AR500 steel is a specific type of abrasion resistant steel.  This has a surface hardness of 477-534 BHN. It is a high-carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison. However, this increase in strength and abrasion resistance will make the steel less malleable.

AR500 steel is one of the more abrasion resistant steels available. As you increase hardness, however, you are creating a more rigid steel. This means that AR500 is less weldable and formable than other types of AR steel. It has the following chemical and mechanical properties:

  • Welding = Decent
  • Machining = Good
  • Abrasion Resistance = Excellent
  • Corrosion Resistance = Good
  • Forming = Fair

Benefits of AR500 Steel Plate

The main benefit of AR500 steel plate, like any abrasion resistant steel, is its ability to resist wear and abrasion. Because of this, it can lead to less down time and can improve the longevity of your equipment by reducing erosion and wear. All of this, in turn, can lead to maximized production time.
