CLASSIFICATIONS: ENiCr3T1-4 per AWS A5.34

This gas-shielded, flux cored, nickel-based electrode, which welds in all positions, has a nominal weld composition of 19% chromium, 3% manganese, 2.5% niobium with a nickel balance. SelectAlloy 82-AP is used for welding alloys 600, 601 and 800 to themselves, to the clad side of joints in steel clad with nickel-chromium-iron alloys and for the dissimilar welding of nickel-based alloys. It is also used for joining carbon steels to nickel alloys and for the surfacing of carbon steels.

APPLICATIONS: Due to its excellent resistance to pitting and stress corrosion cracking in chloride contaminated environments, SelectAlloy 82-AP is ideal for welding in desalination plants. This electrode is also well suited for welding applications that span a wide range of temperatures, from cryogenic to elevated, such as piping, furnace equipment, petrochemical facilities and power generation plants.
