Properties and Applications

Dublex (ferritic-austenitic) stainless steel wire electrode for submerged arc welding of dublex Cr-Ni-Mo stainless steels. Used in combination with SIF 501 and SIF 502 submerged arc welding fluxes. Especially used in welding of acid tanks and pipes, in chemical, petrochemical, paper, shipbuilding and desalination industries. Suitable also for dissimilar welding of dublex stainless steels to carbon steels. High-strength and ductile weld metal exhibits good resistance to pitting, crevice corrosion and stress corrosion cracking in chloride-bearing media.
