SelectAlloy 347-AP

Stainless Steel / Flux Cored / Gas Shielded


Features

  • The added carbon (C) provides higher tensile and creep strength at elevated temperatures.
  • The addition of niobium (Nb) reduces the possibility of intergranular chromium carbide precipitation and thus susceptibility to intergranular corrosion.
  • Designed for welding in all positions where well washed beads can be achieved with minimal weaving.
  • Smooth arc transfer produces minimal spatter.
  • Applications for this alloy type includes welding chromium-nickel stainless steel base metals of similar composition stabilized with either Nb or titanium (Ti).
