SelectAlloy 316LSi-C

Stainless Steel / Metal Cored / Gas Shielded


Features

  • The addition of molybdenum (Mo) improves resistance to pitting and crevice corrosion compared to type 308 stainless steel.
  • 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 benefits include the ability to successfully bridge gaps when part fit up is not as designed, higher travel speeds with subsequent lower heat inputs at equal amperages, and ability to join thin materials.
  • Applications include welding in the pulp and paper industry, chemical and textile processing equipment, furnace parts and in parts exposed to marine environments.
  • Alloy types for welding include 316 stainless and similar alloys, such as A743 and A744 as well as CF-3M and CF-8M.
