SelectAlloy 312

Stainless Steel / Flux Cored / Gas Shielded

Resources

Features

  • Two-phase weld deposit with substantial amounts of ferrite in an austenitic matrix.
  • Produces a finely rippled, equal legged, and well washed bead geometry 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 for this alloy type include welding dissimilar metal compositions of which one component is high in Ni. Even considering the dilution from the austenite forming elements (i.e. nickel), the microstructure remains two-phase and highly resistant to weld metal cracks and fissures.
