Description
  • NIHONWELD NHF-450 is a low hydrogen type hardfacing welding electrode that features excellent hardness, cracking resistance, and heat resistance 
  • Suitable for heavy intermetallic abrasion and light abrasion by soil and sand
  • Weld deposit may be difficult to machine but possible with carbide tools
  • Excellent welder appeal due to smooth and steady arc with minimal spattering, and easy slag removal

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 of bulldozer links, idlers, rollers, and sprockets
  • Preheat at 150ºC and over
  • In the case of multi-layer build-up welding or hardenable steel welding, underlay with low hydrogen type electrode (N-7016 or N-8016)
  • Dry the electrodes at 300-350ºC for 30-60 minutes before use
