SelectAlloy 309LT0-3

Stainless Steel / Flux Cored / Self 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 either the flat or horizontal position where gas-shielding is not possible.
  • Arc transfer is globular, with low spatter, and resulting bead is flat and well washed with a fine ripple surface.
  • 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.
