FCW Sub 310
Description & applications
• Metal cored stainless steel wire for gas shielded arc welding
• 25% chromium - 20% nickel deposit • Enhanced productivity, improved weldability, better wetting properties compared to solid wires
• Excellent weld metal quality and X-ray soundness
APPLICATIONS
FCW Sub 310 is resistant to oxidation and scaling up to 1100°C. It is suitable for welding cast or wrought stainless steels of similar composition and heat resistant ferritic stainless steels.
