AR400 Steel Plate

AR400 steel is a high-carbon alloy steel that is specifically designed for abrasion and wear resistant applications. It has a lower hardness of 360 – 444 BHN. As with other abrasion resistant steels, it does not have a defined chemistry, but rather, grade is determined based on hardness.

We sell our trademark material Amera-Braze® 420 that is made to surpass AR400.

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
  • .125″-.315 offered in 48″-65″ wide cut to your requested length
  • .375”-2.00” offered in standard sizes (96″ X 240″/288”)

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.



All flatness and thickness requirements for AR400 meet standards that are 50% of that specified in ASTM A-6. The mechanical properties match those of ASTM A370.

Industries and Applications
