Abratig 318Si
Description & applications
Low carbon solid rod for TIG welding of stabilised stainless steels (318, 316Ti…). Good intergranular resistant corrosion. Service temperature from -120°C up to +400°C. The TIG process is particularly suited for welding of piping systems, works of fine thinness equal or inferior than 3 mm and for penetration passes.
Main applications: Applied in the petrochemical industries and for sea water applications…
