NHF-600R

Specification

AWS Specification: N/A
JIS Specification: DF2B-600-R
Other Specification: DIN 8555: E2-UM-55-G

Description

Application

Remarks

  • 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
