Selectarc TIG D22/09

This low-carbon solid rod is specifically designed for GTAW (Gas Tungsten Arc Welding) of duplex (austenitic-ferritic microstructure) stainless steels, such as Ur 35N™ or 45N™. It offers exceptional resistance to corrosion in chloride-containing environments, protecting against pitting, crevice, and stress corrosion. This welding wire is suitable for components requiring high strength combined with resistance to corrosive attack. It’s compatible with various duplex stainless steel grades including S31803, S32304 and S32900.

Ideal for welding pumps, vessels, and piping systems utilizing duplex stainless steel alloys. Specifically suited for applications demanding high strength and corrosion resistance, particularly in aggressive environments. The recommended welding parameters (shielding gas flow rates, back shielding) are detailed for optimal results.
