SelectAlloy 317LSi-C

Stainless Steel / Metal Cored / Gas Shielded

Resources

Features

  • The addition of molybdenum (Mo) improves resistance to pitting and crevice corrosion compared to even type 316 alloy due to the nominal ~1 % increase (Mo).
  • Increased silicon (Si) content compared to standard grades of the same alloy composition improves bead wetting and arc stability.
  • Low carbon (C), < 0.03 wt%, minimizes carbide precipitation (sensitization) which makes the weld metal more resistant to intergranular corrosion.
  • Metal cored construction inherently provides better welding performance compared to solid wires of equal or similar AWS classification; benefits include ability to successfully bridge gaps when part fit up is not as designed, higher travel speeds can be achieved with subsequent lower heat inputs at equal amperages, and ability to join thin materials.
  • Applications for this alloy type include welding components of similar composition or multilayer cladding applications in severely corrosive environments.
