Product description
9Cr- 1Mo alloyed GTA (TIG) welding rod for creep resisting steels, subjected to operating temperatures up to 600°C. Suitable for welding P9 / T9 steels in power generation and petrochemical industries. 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. Stick Electrode: EM 285
