1: AR450 steel introduction
Much like AR450 and AR400, AR500 steel is a specific type of abrasion resistant steel. This has a surface hardness of 477-534 BHN. It is a high-carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison. However, this increase in strength and abrasion resistance will make the steel less malleable.

| Application |
Abrasion resistant steel is used in areas where there is likely to be a high degree of abrasion or wear of the steel plate. Typical applications are in truck beds, attachments to diggers and earth movers and in processing applications in the mining industry.
The key quality for wear resistant steels is their hardness. We sell wear plate according to its hardness measured on the Brinnell Hardness Test- usually in 400HB grades. |
