Description and Applications
HJ600B is a low hydrogen type electrode for surfacing worn parts of earth moving equipment, mining machinery, conveyor feed screws and agricultural implements to be used without machinery. Metal deposits’ hardness is about 580∼610Hv. Martensitic matrix microstructure provides excellent wear resistance.
Suitable for the hard facing of mild and alloy steel components.

Guideline in Usage


Electrode should be re-dried at 300360℃ for 60 minutes before use.


Remove dirt such as oil and dust before welding.
