Corodur Corolit E 12 description:
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. The toughness and the hardness are between COROLIT 1 and COROLIT 6. It is more abrasion resistant than COROLIT 6 but more resistant to temperature shocks and tougher than COROLIT 1. The deposit is only machinable by hard faced tools.
APPLICATION
Hardfacing of cutting edges of long knifes and other tools used in the wood, plastic, paper, carpet and chemical industry.
