FCW Sub 347H
Description & applications
• Metal cored stainless steel wire for gas shielded arc welding
• 19% chromium - 9% nickel - niobium stabilised - high carbon deposit
• Enhanced productivity, improved weldability, better wetting properties compared to solid wires
• Excellent weld metal quality and X-ray soundness
APPLICATIONS
FCW Sub 347H is suitable for welding the higher carbon stabilised stainless steels containing 16 to 21% Cr and 8 to 13% Ni. The deposit has a controlled delta ferrite content and can be used above 550°C.
