Typical data and test results for mechanical properties, deposit, or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design, and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.

  • Welding of 2.25% Cr - 1% Mo steel used for super-heater tubes and steam pipes of boilers for electric power plant and marine use, equipment for oil refining industries, and high temperature synthetic chemical industries

  • Dry the electrodes at 325 - 375C for about one hour before use
  • Preheat at 150 - 300C and post heat at 670 - 730C
