Duplex Stainless Steel Electrodes
AWS/ASMEClass E 2209-16
SPECIFICATIONSFA A5.4
VJ 2209 (22.5% Cr, 9.5% Ni, 3% Mo, 0.15% N) is ideal for welding duplex stainless steels like UNS S31803 and S32205. It offers high tensile strength, excellent resistance to pitting and stress corrosion cracking, especially in hydrogen sulfide and chloride environments. Post-weld annealing requires a higher temperature than the base metal. Suitable for pressure vessels, heat exchangers, pipelines, and nuclear equipment.
