Properties and Applications

Rutile-basic type coated hardfacing electrode which deposits Co-Cr-W alloy weld metal. Suitable to use in hardfacing of parts subjected to either the single or combined effect of: heavy metal-to-metal wear or abrasion, high temperatures (ranging from 500°C to 900°C) and corrosive environments. Due to its very higher toughness and shock resistance extends its use for service conditions involving mechanical impacts and thermal shocks. Suitable for plastic extrusion screws, tools to cut paper, cardboard flor coverings, roofing, wood, galvanizing baths. Preferred to use with DC, electrode in positive (+) and possible to use with also AC.
