    Characteristic as below:

    HY Co31(UNS R30031/ Stellite 31) is a cobalt-base, high-temperature super alloy having high tensile and creep properties in pre-cision casting. It is superior in stress-rupture properties to most alloys commercially available, especially at 1700 and 1800°F.

    Processing conditions and application:

    HY Co31(UNS R30031/ Stellite 31) is mainly used in gas turbine engines in areas subject to hot gas erosion.
