Description
  • NIHONWELD NHF-43 is a premium chromium carbide hardfacing electrode specially alloyed with Niobium to create a hard and durable weld deposit that provides exceptional wear resistance to abrasion, impact, and corrosion
  •  Ideal for a wide range of maintenance and repair applications in the construction, mining, agriculture, and manufacturing industries
  • Weld deposit is is non-machinable and can only be grinded
  • Produces a smooth and even weld bead
  • Excellent welder appeal due to smooth and steady arc with minimal spattering, and easy slag removal
  • Comes in special vacuum packed packaging for improved shelf life and top-level welding performance

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.

  • Construction: bucket teeth, grader blades, scraper blades, and cement press screws
  • Mining: shovel teeth, bucket teeth, ripper shanks, wear plates, and crusher jaws
  • Agriculture: plow shares, palmnut press screws, and cultivator blades
  • Manufacturing: dies, punches, and wear plates
  • Preheat at 150ºC and over in general
  • In case of multi-layer build-up welding and welding mother plates with hardening property, under-lay with low hydrogen type electrodes for mild steel
  • Dry the electrodes at 300-350ºC for 30-60 minutes before use
  • Clean weld area properly before welding
  • Keep a medium long arc
  • Oscillation of the electrode with an amplitude up to 3-4 times the nominal diameter results in a very regular and smooth bead
  • The full properties of the alloy is obtainable in two layer deposits
