Cobalt - Base Alloys

Supplier: Wear Protection Services

Corolit 12 DIN 8555: MF 20-50-CTZ DIN EN 14700: T Co 2-50-CTZ This cobalt base-alloy is the toughest, with highest corrosion and thermal resistance of all cobalt-base alloys. The weld deposit is machinable and is used on components that are exposed to high temperatures, corrosion and impact stress, such as valve seats as well as components in the chemical industry. Work hardening up to 45 HRc.

Cobalt - Base Alloys

Corolit 1
DIN 8555: MF 20-55-CGTZ       
DIN EN 14700: T Co 2-55-CGTZ

Corolit 1 deposits a cobalt-base alloy with an austenitic-ledeburitic structure. This is the hardest of the standard cobalt-base alloys. It has a high resistance to corrosion (especially to reducing acids and impact), extreme wear and temperature shocks. The alloy is only machinable by grinding. Best used on wear pads, rotary seal rings, pump sleeves and centerless grinder work rests.

 

Corolit 6
DIN 8555: MF 20-45-CTZ       
DIN EN 14700: T Co 2-45-CTZ

Cobalt-base alloys with an austenitic-ledeburitic structure containing chrome and tungsten carbides. These alloys are resistant against high corrosion and abrasion, high impact stress and extreme temperature shocks. The deposit is machinable by hard metal tools. Best used on steam and chemical valves and on equipment handling hot steel, such as tong bits, hot steel-shear blades, etc.

 

Corolit 6 LC
DIN 8555: MF 20-40-CTZ       
DIN EN 14700: T Co 2-40-CTZ

Cobalt-base alloys with an austenitic-ledeburitic structure containing chrome and tungsten carbides. These alloys are resistant against high corrosion and abrasion, high impact stress and extreme temperature shocks. The deposit is machinable by hard metal tools. Best used on steam and chemical valves and on equipment handling hot steel, such as tong bits, hot steel-shear blades, etc.

 

Corolit 6 HC
DIN 8555: MF 20-45-CTZ       
DIN EN 14700: T Co 2-45-CTZ

Cobalt-base alloys with an austenitic-ledeburitic structure containing chrome and tungsten carbides. These alloys are resistant against high corrosion and abrasion, high impact stress and extreme temperature shocks. The deposit is machinable by hard metal tools. Best used on steam and chemical valves and on equipment handling hot steel, such as tong bits, hot steel-shear blades, etc.
