Bohler CN 22/9 PW-FD description: BOHLER CN 22/9 PW-FD is a rutile Duplex steel all-positional flux cored wire for GMAW the steel grades 1.4462 / S31803. It is suited for joint welding of similar alloyed austenitic-ferritic duplex steels as well as for dissimilar joints and weld cladding. The weld metal is resistant against intergranular corrosion (wet corrosion up to +250°C). It features a good resistance against pitting (CPT ASTM G48/method A (24h) up to 25°C) and stress corrosion cracking in chloride-containing fluids i.e. sea water. BOHLER CN 22/9 PW-FD is an ideal completion of our high class range of Duplex Filler Metals. It is designed to satisfy the high demands of offshore fabricators, shipyards building chemical tankers as well as the chemical/petrochemical, pulp and paper industries. Service temperatures between –46°C and +250°C are usable. Good wetting characteristics (less grinding), easy slag release, very little temper discoloration & bead oxidation (less pickling expenses), and smooth and clean weld finish help to save additional costs especially when multi-pass welding Duplex stainless steels.
