ER90S-B9
AWS/ASME SFA-5.28:Description:
TIG welding wire rod that is 9Cr-1Mo wire modified with niobium (columbium) and vanadium designed to provide strength, toughness, fatigue life, oxidation resistance and corrosion resistance at elevated temperatures.
This welding wire rod is used for welding creep-resistant steels, especially for welding P91/T91 steels in turbines, tanks and thermal equipment. Its weld metal can be serviced in hot hydrogen environment, especially in oil refineries and is suitable for working conditions up to 650 ˚ᶜ for a long time.
