FCW S 329
Description & applications
• Rutile flux-cored stainless steel wire for gas shielded arc welding
• 25 % chromium - 4 % nickel - high carbon deposit
• Attractive bead appearance, automatic slag release, very good penetration and high productivity
• Excellent X-ray soundness
• Maximum performances in the horizontal and downhand positions
• Welded with classical economical Ar-CO2 mixtures or CO2
APPLICATIONS
FCW S 329 is suitable for high temperature application where the nickel content of the filler material must be kept as low as possible. It is used for joining refractory Cr-Al-Si steels - as a general rule for stainless steels containing 8 to 24% chromium with silicon and/or aluminium additions - or for cladding corrosion resistant overlays.
