Item Details

  • This metal cored, stainless steel electrode is composed of 24% chromium, 13% nickel and 0.8% silicon with a maximum carbon content of .03%. The higher silicon level improves bead wetting while the lower carbon content minimizes carbide precipitation and makes the weld metal more resistant to intergranular corrosion.


  • CWB CSA W48-18 EC309LSi N/A
  • Produces smooth, well washed beads.
  • Ideally suited for making small butt, lap and fillet welds on thin material at elevated travel speeds.
  • Produces little or no slag and virtually no spatter.
  • Handles poor fit-up.
  • Offers higher deposition rates than equivalent solid wire.


  • SelectAlloy 309LSi-C is utilized in the welding of refinery and chemical processing equipment as well as furnace and auto exhaust parts.
  • This electrode welds Type 309 stainless steel and may be used to join carbon and low alloy steels to austenitic stainless steels.
