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.

  • Valve sleeves of high pressure pump
  • Cutting knives
  • Liner sleeves
  • Valve seats and dies
  • Preheat at 300ºC and over
  • Effective to postheat at 600ºC and to slow cool after welding to prevent cracking
  • Dry the electrodes at 150-200ºC for 30 ? 60 minutes before use
  • Non-forgeable and can be machined with difficulty using carbide tools
