FCW V 309L
Description & applications
DESCRIPTION
- Rutile flux cored stainless steel wire for gas shielded arc welding
- 24% chromium - 13% nickel - low carbon deposit
- Specifically designed for out-of-position welding
- Attractive bead appearance, very good penetration and high productivity
- Excellent X-ray soundness
- Maximum productivity for completion of vertical welds
- Welded with classical economical Ar-CO2 mixtures or CO2
APPLICATIONS
- Welding stainless steels of similar composition or ferritic stainless steels.
- Joining stainless steels to mild and low-alloyed steels.
- Rebuilding and buffering before cladding or hardfacing.
- Maintenance on « hard-to-weld steels ».
