Select 308LSi (GTAW)

Stainless Steel / TIG (GTAW) / Gas Shielded

Resources

Features

  • Low C, < 0.03 wt%, minimizes carbide precipitation (sensitization) which makes the weld metal more resistant to intergranular corrosion.
  • Increased Si content compared to grades of similar alloy composition improves bead wetting.
  • Actual chemistry certificate with calculated ferrite number (FN) available for each lot.
  • Embossed identification markings on both ends of the electrode.
  • Applications for this alloy type include welding austenitic alloys of similar composition, 301, 302, 304, 304L, 308, and 308L. These alloys are commonly found in chemical, paper, textile, food service equipment, and pharmaceutical industries.
