Sandvik 22.9.3.LR description: Sandvik 22.9.3.LR is a covered electrode with rutile-acid coating for welding of duplex (ferritic-austenitic) stainless steels of UNS S31803/S32205 type (e.g. Sandvik SAF 2205). It is characterized by very good welding properties and gives an austenitic-ferritic chromium/nickel/molybdenum weld metal with an extremely low carbon content for service temperatures up to 250oC (480oF). Spray transfer gives a bead with a finely rippled surface. There is little spatter and very good slag removal.
