Abrex 400 wear plate properties

Abrex 400 steel is abrasion resistant steel or wear resistant steel plate (wear 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. We can supply Abrex 400 NM400 wear plates in HARDOX, RAEX, JFE, XAR, BIS standards.

 

Abrex 400 wear plate: Yields for 400HB steel are in the region of 100MPa with tensile strengths of about 1250MPa.

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. We generally provide good cold bending properties and good weldability. Weldability is not generally reduced as the hardness increases.

 

Wear resistant steel is not appropriate for use at temperatures over 250 degree C as the heat can cause changes to the material properties.
