SelectAlloy 347

Stainless Steel / Flux Cored / Gas Shielded

Resources

Features

  • The added carbon (C) provides higher tensile and creep strength at elevated temperatures.
  • The addition of noibium (Nb) reduces the possibility of intergranular chromium carbide precipitation and thus susceptibility to intergranular corrosion.
  • Designed for welding in either the flat or horizontal position in both 100% CO₂ or 75-80% Ar/balance CO₂ shielding gas.
  • Smooth arc transfer and self-releasing slag that peels freely to ensure that clean up time is minimized.
  • Applications includes welding chromium-nickel stainless steel base metals of similar composition stabilized with either Nb or titanium (Ti).
