OK Autrod 308LSi

OK Autrod 308LSi is a continuous solid corrosion‑resisting chromium‑nickel welding wire designed for austenitic stainless steel (18% Cr‑8% Ni) applications. It offers good general corrosion resistance, low carbon content for reduced intergranular corrosion risk, and higher silicon for improved wetting.

Key Features

• Solid corrosion‑resistant Cr‑Ni wire (18% Cr, 8% Ni).
• Low carbon alloy reduces intergranular corrosion.
• Higher silicon content enhances wetting and welding stability.
• Suitable for chemical, food processing, pipe, tube, and boiler fabrication.
