1.6mm Alloy C22 TIG Filler Weld Star Pack 5Kg

Stock Code: FAW00011619
Manufacturer Part No: 6011100599

Descriptions

Corrosion-Resistant Applications

Weld Star Alloy C22 is a premium nickel-chromium-molybdenum TIG wire formulated for superior corrosion resistance in highly aggressive environments. It is engineered for the welding of C22, 625, 825, and other corrosion-resistant alloys, as well as for dissimilar welds in super duplex and super austenitic stainless steels.

This alloy is ideally suited for cladding and overlays on lower alloy steels where excellent resistance to pitting, crevice corrosion, and stress corrosion cracking is required. The absence of niobium (Nb) ensures a clean, tough weld deposit suitable for the harshest service conditions.
