NHF-650B

Specification
AWS Specification: N/A
JIS Specification: DF2B-650-R
Other Specification: DIN 8555: E2-UM-55-G
Description
  • NIHONWELD NHF-650B is a rutle type hardfacing welding electrode that is easy to use with 100% metal recovery 
  • Deposits an air-hardening martensitic steel weld metal that exhibits high resistance to severe abrasion and moderate impact
  • Alloying in the flux coating results in a high carbon martensitic weld matrix microstructure
  • Weld deposit is is non-machinable and can only be grinded
  • Smooth running properties exhibiting excellent weld pool and slag control in all positions
  • 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.

  • Conveyor feed screws
  • Pump housings
  • Augers
  • Earth scoops
  • Buckets
  • Palm oil mill screws
  • Grousers
  • Earth moving equipment
  • Agircultural implements
  • Remove mill scale, heavy rust, fatigued, or deformed metal before welding
  • Preheat heavy sections or low alloy steels to 100ºC ? 300ºC is suggested for improved weldability and heat affected zone crack resistance
  • Where rebuilding is necessary for a heavily worn component NHF-300 or NHF-350B is recommended before hardfacing the final 1-3 layers with NHF-650B
