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). 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 45
HRC.
