Exaton 22.9.3.LR is a chromium-nickel-molybdenum-nitrogen covered electrode with rutile coating for welding of 22-23%Cr duplex (ferritic-austenitic) stainless steels (e.g. Sandvik SAF 2205). The ferrite content in the all weld metal is approximately 40 FN according to WRC-92. The electrode provides excellent arc stability, low spatter, self peeling slag and smooth weld bead finishing. The all weld metal is characterized by high strength and very good resistance against pitting corrosion (in chloride containing media) as well as stress corrosion cracking. Exaton 22.9.3.LR is used for welding of duplex and lean duplex stainless steels in service temperatures up to 280°C (536°F). Typical base materials welded include ISO: 1.4462, 1.4362, 1.4162, 1.4662, 1.4460 and 1.4417.
