Select ER308LSi

Stainless Steel / Solid / Gas Shielded


Features

  • Increased Si content compared to grades of similar alloy composition improves bead wetting and arc stability.
  • Low C, < 0.03 wt%, minimizes carbide precipitation (sensitization) which makes the weld metal more resistant to intergranular corrosion.
  • Unique manufacturing techniques provide enhanced arc stability and stable feeding.
  • 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.
