Stellite 13

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 13 was designed for good general resistance to wear, erosion, and oxidation. Stellite 13 is used in a range of applications where a strong balance of wear and corrosion properties are required while also retaining good ductility and machinability. It has improved corrosion resistance relative to Stellite grades such as Stellite 6, Stellite 12 and Stellite 3.
