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.
In addition to its general characteristics of being formable, while maintaining good abrasion resistance, AR400 steel also has the following mechanical properties:
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.
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:
