What is AR400 Steel?
AR400 is specifically designed for abrasion and wear-resistant applications. AR400 has a typical hardness range of 360-444 BHN, which is slightly lower than AR450. As with other abrasion-resistant steels, it does not have defined chemistry, but rather, the grade is determined based on hardness.
AR400 Steel Plate Sizes
- .125"-.315 offered in 48"-65" wide cut to your requested length
- .375”-2.00” offered in standard sizes (96" X 240"/288”)
Properties of AR400 Steel Plate
In addition to its general characteristics of being formable, while maintaining good abrasion resistance, AR400 steel also has the following mechanical properties:
- Machining = Fair
- Bending = Good
- Corrosion Resistance = Good
- Welding = Excellent
- Wear Resistance = Great
- Excellent resistance to both impact and sliding abrasion at a moderate cost.
- Recommended for: liners for mining and material handling equipment like dump trucks, material transfer chutes, storage bins, buckets, and hopper
AR400 Steel Requirements
All flatness and thickness requirements for AR400 meet standards that are 50% of that specified in ASTM A-6.
Benefits of AR400 Steel Plate
When zeroing in on what abrasion resistant steel is best for your applications, it’s important to note that each grade reacts differently to many fabricating processes. AR400 steel plate is excellent for applications in which abrasion resistance is required, but formability and weldability are a must. Because of these properties, it can be used for a variety of different applications. It is particularly good in applications where there may be impact or sliding abrasion.

Industries and Applications
Because of its unique properties, AR400 has applications in a variety of different industries and for all types of general uses. It is often used in:
- Mining
- Material Handling Equipment
- Dump Truck Liners
- Material Transfer Chute Liners
- Storage Bin Liners
- Bucket Liners
- Hoppers
- Aggregate
