SelectAlloy 309L-AP LHCr+6

Stainless Steel / Flux Cored / Gas Shielded

Resources

Features

  • Low C, < 0.04 wt%, minimizes carbide precipitation (sensitization) which makes the weld metal more resistant to intergranular corrosion.
  • Designed for welding in all positions where well washed beads can be achieved in both 100% CO₂ or 75-80% Ar/balance CO₂ shielding gas.
  • Smooth arc transfer and self-releasing slag that peels easily to ensure that clean up time is minimized.
  • Applications for this alloy type include welding dissimilar metal, such as type 304 SS to mild steel, cladding mild steel or type 304 base metals where corrosion requires to be enhanced, and welding of the stainless steel side of type 304 claddings.
  • This product has been specially formulated to reduce hexavlent chromium in the fume compared to standard cored and coated stainless electrodes.
