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.

What is metal abrasion?
When materials run against one another for an extended period of
time, abrasion occurs. Sometimes, abrasion is intentional, as is
the case with blasting, sanding, or grinding. But, when it’s
unintentional, it can lead to structural or component failure.
While steel in general stands out for its resistance to abrasion,
not all steels are created equal, and some steels—abrasion
resistant steels—are particularly suited for applications or
environments where abrasion is expected.
