Typical Properties of AR400
AR400 is “thru-hardened”, abrasion resistant, alloy wear plate. Hardness range is 360/440 BHN with a nominal hardness of 400 BHN. Service Temperature is 400°F. This plate product is intended for use in applications where a good balance of formability, weldability, toughness and abrasion resistance are required. Abrasion resistant steels are typically sold to hardness range and not a fixed chemistry. Slight variations in chemistry are present depending upon the producing mill. Applications may include use in mining, quarries, bulk material handling, steel mills, and pulp & paper industries. Wear plate products are designed for liner applications; they are not intended for use as self-supporting structures or lifting devices.
Typical Properties of AR500
AR500 is a “thru-hardened”, abrasion resistant, alloy wear plate. Hardness range is 470/540 BHN with a nominal hardness of 500 BHN. This plate product is intended for use in applications where a good balance of impact, toughness and abrasion resistance are required. Abrasion resistant steels are typically sold to hardness range and not a fixed chemistry. Slight variations in chemistry are present depending on the producing mill. Applications may include use in mining, quarries, bulk material handling, steel mills, and pulp & paper industries. Wear plate products are designed for liner applications; they are not intended for use as self-supporting structures or lifting devices.

Abrasion Resistant (AR) steel plate is typically made in the as-rolled condition. These types/grades of steel plate products have been developed specifically for long service life in harsh conditions. AR products are suitable for a variety of applications in areas such as mining/quarrying, conveyors, material handling and construction, and earthmoving. Designers and plant operators choose AR plate steel when striving to extend service life of critical components, and reduce the weight of each unit put into service. The benefits of employing wear-resistant plate steel in applications involving impact and/or sliding contact with abrasive material are immense.
Abrasive resistant alloy steel plates generally offer good resistance to sliding and impact abrasion. The high carbon content in the alloy increases the hardness and toughness of the steel, making it an ideal material for applications that require high impact or high abrasion resistance. It is possible to get high hardness with a high carbon steel, and the steel will have good resistance to penetration. However, the wear rate will be rapid compared to heat treated alloy plate because high carbon steel is brittle, so particles can be more easily torn from the surface. As a result, high carbon steels are not used for high wear applications.
