AWS: SFA 5.5 E9015-B3 Electrodes for Creep Resisting Steels
Low hydrogen electrode depositing 2.25Cr – 1Mo weld metal, display remarkable o strength and creep resistance at elevated temperatures up to 575 C. It is used for welding 21⁄4 Cr-1 Mo creep resistant steel and Cr-Mo-V steels resistant to hydrogen under pressure as well as for cast steels of a similar composition to the weld metal. Typical applications include steam boiler construction, welding of steam and super- heater piping, power plants, oil refinery and chemical plants.
