Duraplate : composite wear plate

Stringer beads
Homogeneity of the deposit, Regular appearance
High metallurgical quality

Duraplate is the reference brand for composite wear plates. The Duraplate life cycle can be over ten times longer than that of traditional abrasion resistant steels. It is an optimum way to protect equipments subject to extreme wear conditions while spacing out maintenance operations.

Duraplate comprise a base plate of construction steel and a wear resistant coating applied by arc welding in order to offer exceptional resistance to abrasive wear.
This coating is made with cored wires specially developped by Welding Alloys.

It is a true composite plate, weldable, suitable for forming, corrosion and pressure resistant. Most wear issues can be addressed by adjusting the chemical composition of each overlay and by combinating thicknesses of the two constituents. The wear resistant coating is manufactured on large size plates, according to ISO 9001 certified procedures that guarantee homogenous and high volumes of carbides.

Stringer beads applied by arc welding  entail homogeneity of the deposit (fine carbides), regular thickness, smaller  and smoother cracks and low dilution in the base plate.

Forming

The exceptional quality of the Duraplate wear plate makes it suitable for cold forming, according to specifications that depend on the coating thickness. When the plate is heated up to over 1200°C, it can be hot stamped and it retains features unchanged.

Welding

All classical welding procedures can be applied to Duraplate. The coating can be repaired or completed with Durcor electrodes or wires (same composition than the filling metals).
