COROLIT® E 21

CLASSIFICATION

DIN EN 14700
E Co1

GENERAL CHARACTERISTICS

AC-weldable hardfacing electrode with an alloyed core and a recovery of 160 %. The deposit is a cobalt base alloy of high tenacity as well as extreme corrosion and heat resistance. The weld metal is highly resistant to impact and is work-hardening up to 45 HRC.
Working temperature should be kept between 400° and 600°C, depending on base material and type of construction. Slow cooling, if necessary oven cooling, is recommended for low alloyed and austenitic steels. Subsequent heat treatment (stress relief at 700°C approx.) is not necessary, except on large structures.

APPLICATION

Hardfacing of cutting edges of long knifes and other tools used in the wood, plastic, paper, carpet and chemical industry.

COROLIT® E 12

CLASSIFICATION

DIN EN 14700
E Co3

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.

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.

COROLIT® E 1

CLASSIFICATION

DIN EN 14700
E Co3

GENERAL CHARACTERISTICS

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.

APPLICATION

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.
