AR 400 Plate
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.
400 HB steel is over 3 times harder than mild steel (120HB), but only a third as hard as
stainless steel (150HB). Example uses are for construction machinery, skips, bulldozers
and excavators, buckets and conveyors.
Steels with a hig HB rating (Briness Hardness) are intended for applications where wear
or abrasion resistance is important. The benefit of using an abrasion resistant steel is that
the plant, machinery or constructions working life can be extended considerably. This can
significantly improve the reliability, durability and safety of structures and equipment. It
also helps to reduce the maintenance costs associated with wear and breakdown of plant.
The steel is quenched which provides wear resistance; in order to improve hardness it
may also be tempered. Lower HB's generally provide good cold bending properties and
good weldability. Weldability is not generally reduce
