Hard coating electrode
Application/properties:
Rutile-covered electrode is suitable for depositing hardfacing overlays on components subject by metal to metal. The weld metal is resistant to impact and high compressive stresses. It is weldable by AC (OCV 70V) and DC+ in the flat and vertical up position.
