FCW SB 310
Description & applications
• Basic flux cored stainless steel wire for gas shielded metal arc welding
• 25% chromium - 20% nickel deposit
• Exclusive slag system and fine tuning of the compositional balance insure maximum resistance to hot cracking under restraint
• Attractive weldability
• Excellent X-ray soundness, ductility and impact toughness
• Maximum performances in the horizontal and downhand positions
• Welded with classical economical Ar-CO2 mixtures
APPLICATIONS
FCW SB 310 is resistant to oxidation and scaling up to 1100°C.It is suitable for welding stainless steels of similar composition, especially in those applications where solid wires or rutile welding consumables are unsuitable due to cracking.
Joining of heat resistant ferritic alloys
