SelectAlloy 347-C

Stainless Steel / Metal Cored / Gas Shielded

Resources

Features

  • The addition of niobium (Nb) reduces the possibility of intergranular chromium carbide precipitation and thus susceptibility to intergranular corrosion.
  • Metal cored benefits include the ability to successfully bridge gaps when part fit up is not as designed, higher travel speeds with subsequent lower heat inputs at equal amperages, and ability to join thin materials.
  • Applications for this alloy type includes welding chromium-nickel stainless steel base metals of similar composition stabilized with either Nb or titanium (Ti).
