Stellite®21 consists of a CoCrMo alloy matrix containing dispersed hard carbides. These carbides can increase the strength of the alloy and increase its hardness, but also reduce the ductility. It has excellent thermal shock resistance and mechanical shock resistance, and obtains the best high temperature strength through solution heat treatment at a temperature of 1200 to 1240ºC (2190-2265ºF), followed by quenching and aging in the temperature range of 700-1150°C (1290-2100°F).

Stellite®21 can be cast, powder metallurgy treated or used as welding overlay. Recommended for applications involving cavitation, corrosion, corrosion and/or high temperature, such as petrochemical and electric valve trim

generation. Because of its good impact resistance, it has been widely used in the manufacture of forging or hot stamping dies.
