Our organization offers its clients with an extensive range of Wear and Abrasion Resistant Steel Plates. We sell wear plates according to its hardness measured on the Brine Hardness Test – usually in 400 HB and 500 HB grades. If your specification is to the Rockwell Test we can also advise. Steels with a high HB rating (Brinell Hardness) are intended for applications where wear or abrasion resistance is important. The benefit of using an abrasion resistant steel is that 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.
400 HB steel is over 3 times harder than mild steel (120 HB), but only a third as hard as stainless steel (1250 HB). Example uses are for construction machinery, skips, bulldozers and excavators, buckets and conveyors. 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 weld-ability. Weld-ability is not generally reduced as the hardness increases.
Wear resistant steels are not appropriate for use at temperatures over 250°C as the heat can cause changes to the material properties. Testing is undertaken by firing 10 mm steel or tungsten carbide ball at 29 kN and the size of the resulting indentation is measured. Tests are carried out according to EN ISO 6506 or ASTM E10. The figures below are representative of 15 mm thick 400 HB and 500 HB plates.
