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. |
