NOTE:

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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.

  • Hardsurfacing of various wheels, shafts, and gears
  • Preheating is not necessary
  • In the case of hard surfacing on large size weldments, low alloy steel and high carbon steel, preheat at 150ºC and over
  • The groove repairing is prone to slag inclusion, so adjust the holding angle of the electrode
  • Machining and quenching is possible
