COROLIT® E 6
CLASSIFICATION
DIN EN 14700
E Co2
GENERAL CHARACTERISTICS
AC-weldable hardfacing electrode with a rutile-basic coating and an alloyed core. The deposit is a cobalt base alloy of austenitic-ledeburitic structure with embedded Cr-W- carbides. The weld metal is highly resistant to corrosion, impact, abrasive wear as well as thermal shocks and heavy mechanical impact. Good aptitude for polishing and machining.
APPLICATION
Due to its above-mentioned characteristics COROLIT E 6 is particularly recommended for use on steam valves, hot shear blades, hot pressing dies, pumps for high-temperature liquids, etc.
