Description
  • NHF-600R is an easy-to-use 100% recovery hardfacing alloy electrode
  • Deposits an air-hardening martensitic steel weld metal
  • Exhibits high resistance to severe abrasive conditions and absorbs moderate impact forces
  • Smooth running with excellent weld pool and slag control
  • Suitable for the hardfacing of mild and alloy steel components

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.

  • Conveyor feed screws
  • Pump housings
  • Augers
  • Earth scoops
  • Buckets
  • Palm oil mill screws
  • Grousers
  • Earth moving equipment
  • Agricultural implements and mixing paddles
  • Self air-hardening deposit is machinable by grinding only
  • Removal of mill scale, heavy rust, fatigued, or deformed metal is advisable
  • Preheat of heavy section or low alloy steels to 100ºC ? 300ºC is suggested for improved weldability and heat affected zone crack resistance
  • WheN rebuilding is necessary, for a heavily worn component NHF-300 or NHF-350B is recommended before hardfacing the final 1-3 layers with NHF-600R
