What is AR 400 Wear Plate？

AR 400 Wear Plate is a popular abrasion-resistant steel grade that combines through-hardness with good levels of ductility and formability. AR400 steel plate has a surface hardness of 360–440 BHN. It is ideal for moderate to heavy wear applications, such as bucket components, dump truck bodies, and construction equipment. Also referred to as AR400F (formable). Composition and hardening processes vary between mills, and mill test reports are supplied with each order.

AR400 steel, known for its High Strength and remarkable resilience, is a type of abrasion-resistant steel plate designed to provide exceptional wear resistance in various demanding applications.

The Significance of the “400” in AR400
The “400” refers to the Brinell Hardness Number (HBW)—a standardized scale measuring material resistance to surface indentation.

AR400 = ~400 HBW

AR450 = ~450 HBW

AR500 = ~500 HBW

At around 400 HBW, AR400 provides excellent wear protection while still maintaining enough ductility to allow bending, forming, and welding. It’s not the hardest—but that’s why it works in so many applications. It’s the best compromise between hardness and usability.

Comparing AR 400 with Other Abrasion Resistant Steels

Prosaic Steel & Alloys is one of the primary manufacturers of AR400 Abrasion Resistant Steel Plate the company has much experience in manufacturing and retailing of AR400 Abrasion Resistant Steel Plate and the company also manufactures other grade products such as Wear Resistant Steel Plates 400HB and 500HB used in many industries such Pressure Vessels and Boilers and Power Generation and Oil and Gas Industry both products are similar to each other because both products are using similar industries but it’s different there grade and chemical and mechanical properties
