What Does Stellite Mean?
Stellite refers to a classification of a group of alloys that contain chromium and are particularly designed to be resistant to corrosion and wear and tear. Stellite alloys also usually contain tungsten or molybdenum and carbon. Several stellite alloys contain at least four to six elements.
Corrosionpedia Explains Stellite
Stellite alloys are used for a wide range of applications, including:
- Manufacturing saw teeth and acid-resistant machine parts
- Manufacturing poppet valves and valve seats
- Producing exhaust valves for internal combustion engines
- Producing M60 and M2HB machine gun barrels
- Cast structure production for dental prosthesis
- Manufacturing turning tools for lathes
- Facilitating difficult cut patterns in stainless steel
Tungsten and molybdenum are often found in stellite alloys, where they serve to provide additional strength to the matrix and improve general corrosion resistance, particularly in reducing non-oxidizing conditions.
