FCW Sub 22 9 3LS
Stainless steel flux-cored wire for submerged arc welding
Product description
Stainless steel flux-cored wire for submerged arc welding
Austenitic-ferritic deposit type 22% chromium – 9% nickel – 3% molybdenum – nitrogen – low carbon
Excellent slag removal, even at the bottom of chamfers, good bead appearance
High deposition rates, high deposition rates, good wetting properties and flexible parameter settings enable significantly higher productivity than corresponding solid wires
Mineral additions to the filler improve both mechanical properties and resistance to cracking
Very good radiographic quality
Product application instructions
APPLICATIONS
FCW Sub 22 9 3LS is suitable for joining and plating duplex stainless steels of the corresponding grade, as well as for heterogeneous joints between these steels and other stainless steels or non/low-alloy steels.
