FCW Sub 22 9 3LG

Slag-free stainless flux-cored wire for gas-shielded arc welding

Product description

 Slag-free stainless flux-cored wire for gas-shielded arc welding

 Austeno-ferritic deposit of the 22% chromium – 9% nickel – 3% molybdenum – nitrogen – low-carbon type

 Increased weldability and productivity compared with corresponding solid wires

 Very secure penetration, good wetting, excellent radiographic quality

 High welding speed in horizontal position

 Can be welded under pure argon, avoiding the use of nitrogen-doped gases

Product application instructions

APPLICATIONS

FCW S 22 9 3LG is suitable for joining and plating duplex stainless steels of the corresponding grade, as well as for heterogeneous assemblies between these steels and other stainless steels or non/low-alloy steels.
