Properties and Applications

Austenitic-ferritic wire electrode for submerged arc welding of stainless steels to unalloyed or low-alloyed steels, subjected to operating temperatures up to 300°C. Used in combination with SIF 501 and SIF 502 submerged arc welding fluxes. Low carbon content increases resistance to intergranular corrosion. Suitable to use also for buffer layer on carbon steel before welding with 308 and 308L to reach 304 and 304L surface layer.
