Description

Application

Remarks

  • Preheating is not necessary
  • In the case of multi-layer welding on low alloy and high carbon steel, preheating over 150ºC is required
  • Dry the electrodes at 300-350ºC for 30-60 minutes before use
  • Quenching after machining is possible

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.
