AR400 is a “thru-hardened”, abrasion resistant, alloy wear plate. Commonly used in mining, quarries, bulk material handling, steel mills, and other industries that require durability, resistance to wear and high-strength.Common uses for AR400 steel: Armor plate for combat robotics, sprockets/gears, wear plates on heavy equipment, and shooting targets.

The hardness range of our AR400 is 360/440 BHN with a nominal hardness of 400 BHN. Service temperature is 400°F. Abrasion-resistant steels are generally sold based on hardness range and not on a fixed chemistry. Slight variations in chemistry are present depending upon the producing mill. Our wear plate products are typically designed for liner applications. We do not recommend them for use as self-supporting structures or lifting devices.
