Product description
High-alloyed, GTA (TIG) welding rod for creep, oxidation and corrosion resistant Cr-Mo-V-Nb alloyed steels, subjected to operating temperatures in 650°C. Suitable for welding P91 and T91 steels used in steam generators, turbine rotors, boiler, piping in refineries, chemical industry and thermal power generation industry. Due to it's high steam and hot hydrogen corrosion resistance, particularly used in root and cap passes of in steam generators, boilers, pressure vessels and piping in refineries, where high X-ray quality is required. Observe directions of pre- and post-weld heat treatment of base metal.
