Description / Abstract:

Form:

This specification covers a corrosion and heat resistant cobalt alloy in the form of investment castings.

Application:

Primarily for small parts, such as turbine blades and vanes, requiring high strength up to 1500°F (815°C) and oxidation resistance up to 2000°F (1095°C). Although difficult to machine, this alloy is more machinable than other similar cobalt-chromium-nickel alloys. Exposure to elevated temperatures may cause hardening of this alloy; e.g., exposure to approximately 1475°F (800°C) for 50 hr may result in hardness as high as 32 HRC.
