COROLIT® E 1
DIN EN 14700
AC-weldable hardfacing electrode with 160% recovery 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. The deposits are only mechinable by grinding.
Due to its above-mentioned characteristics COROLIT E 1 is particularly recommended for use on steam valves, hot shear blades, hot pressing dies, pumps for high-temperature liquids, etc.
