Nominal Composition (Mass %) and Physical Properties
|V, Fe, Si, Mn
Stellite cobalt-based alloys consist of complex carbides in an alloy matrix. They are resistant to wear, galling, and corrosion and retain these properties at high temperatures. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix.
Stellite 694 is a cobalt-chromium alloy which has a high tungsten content to ensure high matrix strength at elevated temperatures (up to 1148oC or 2100oF). This alloy exhibits good resistance to wear, creep, erosion, thermal fatigue, and oxidation. The principal application is for hard-facing turbine blade interlock surfaces. Used in gas turbine parts where a higher hardness than Stellite 31 is required.
