SAF Lexal T 22 9 3 N description: LEXAL T 22 9 3 N is an alloyed rutile flux cored wire, suitable for the joining and cladding of corrosion resistant ferritic-austenitic duplex steels. The weld metal consists of about 30% ferrite and 70% austenite and is particularly resistant to pitting, crevice corrosion cracking in chloride and hydrogen sulphide bearing media. Principal applications include the construction of chemical plants and offshore weldments for operating temperatures up to 250C. Due to its fast-freezing slag, LEXALT 22 9 3 N is used for welding in the horizontal (PC), overhead (PE) and vertical-up (PF) positions.
