Use

Iron-based carbide cored welding wire, containing 50–60% WC, is suitable for applications involving severe wear combined with moderate impact.

Titanium carbide–cored welding wire is suitable for surfacing applications on workpieces that involve crushing highly hard and coarse materials; it exhibits excellent crack resistance after welding. For example, when used for surfacing the squeeze rolls of roller presses, its wear resistance outperforms that of niobium carbide–cored wire.

Niobium carbide–cored welding wire, suitable for surfacing applications on workpieces that require hardfacing to withstand highly abrasive and coarse materials; exhibits crack-free welds, such as in the surfacing of extrusion rolls for roller presses.

Complex carbide-type high-chromium cast iron cored wires containing Vb and V retain excellent resistance to severe wear even at elevated temperatures.

Vanadium carbide– and chromium carbide–based flux-cored welding wires exhibit low spatter loss and significantly superior wear resistance compared with chromium carbide–based wires.

High-concentration composite carbide-type high-chromium cast iron flux-cored welding wire containing W, V, Nb, and Mo, suitable for surfacing of workpieces requiring high-temperature resistance and severe wear resistance.

A flux-cored welding wire made of complex carbide-type high-chromium cast iron containing 7% Nb, primarily used for surfacing the wear-resistant working layer in cement and slag applications.
