OK Tigrod 308LSi

OK Tigrod 308LSi is a corrosion‑resistant chromium‑nickel TIG rod designed for welding austenitic 18% Cr 8% Ni alloys. It offers good general corrosion resistance, low carbon content to reduce intergranular corrosion risk, and higher silicon for improved wetting.

Key Features

• Austenitic rod with approx. 8 % ferrite, 19 % Cr ‑ 9 % Ni composition
• Low carbon content for enhanced resistance to intergranular corrosion
• Higher silicon improves weld wetting and overall weldability
• Suitable for chemical, food processing, pipe, tube and boiler applications
