SelectAlloy 312-AP

Stainless Steel / Flux Cored / Gas Shielded

Resources

Features

  • Two-phase weld deposit with substantial amounts of ferrite in an austenitic matrix.
  • Designed for welding in all positions where well washed beads can be achieved with minimal weaving in both 100% CO₂ or 75-80% Ar/balance CO₂ shielding gas
  • Smooth arc transfer produces minimal spatter.
  • 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.
