NHF-650B

Specification

AWS Specification: N/A
JIS Specification: DF2B-650-R
Other Specification: DIN 8555: E2-UM-55-G

Description

Application

Remarks

  • 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

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.
