Product description
– Rutile-type stainless flux-cored wire for gas-shielded arc welding
– 24% chromium – 13% nickel – 3% molybdenum – low-carbon deposit
– Attractive, spatter-free weldability, outstanding arc stability and pay-off quality
– Automatic slag removal, good bead appearance and excellent radiographic quality
– High productivity for welding in horizontal position
– Can be welded under mixed gas or CO2
Product application instructions
APPLICATIONS
– Joining steels of corresponding grade or ferritic stainless steels
– Joining stainless steels with non- or low-alloy steels
– Reconstitution or undercoating before plating or reloading
– Repair work on steels with limited weldability
Examples:
Heterogeneous joints between CrNiMo stainless steels and non/low-alloy CMn steels, for service temperatures up to 350°C FCW S 309LMo benefits from greater dilution tolerance than 309L due to its higher degree of alloying and higher ferrite content in the deposited metal. Compared with 312, it has a better mechanical strength/ductility ratio.
