SelectAlloy 625-AP

Nickel Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Designed for welding in all positions with excellent slag release in both 75-80% Ar/balance CO₂ or 100% CO₂ shielding gas
  • Iron (Fe) is less than 1 wt% to further enhance corrosion resistance.
  • Exceptional mechanical properties and low temperature ductility make this product suitable for welding 9% Ni-steels for cryogenic service.
  • Can be used to clad the surface of carbon steels to impart superior corrosion resistance and for joining nickel based alloys to steel.
  • Typically used in marine applications for corrosion resistance, for cladding heat exchange and reactor vessels, and for welding LNG storage and conveyance equipment.
