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.

  • Hardfacing applications on parts subject to mineral abrasion, such as conveyor screws, mixer blades, concrete pump parts, stirring and agitator components, slurry pumps, and excavator bucket edges
  • Hold electrode as vertically as possible
  • Keep a short arc
  • Preheating is not necessary
  • For multi-pass applications, a cushion layer with NSS-307 or NHF-Cromang is recommended in order to prevent hardening cracks in the weld deposit
  • Re-dry electrodes that got damp for 2 hours at 300ºC
  • Machinable by grinding only
  • Not suitable for impact conditions
