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.

  • Hold electrode as vertically as possible, keep a short arc
  • Preheating of non-alloyed steels is not necessary
  • Preheat heavy parts and high-tensile base materials to 250-350C. If more than 3-4 layers are needed, apply the softer electrode NHF-300 for build up
  • Deposit is only machinable by grinding
  • Tools in the earth moving industry
  • Crushing Plants
  • Cold and hot working tools
