Stellite grade 6
Stellite alloys are a group of cobalt-chromium ‘super-alloys’ consisting of complex carbides in an alloy matrix predominantly designed for high wear resistance and superior chemical and corrosion performance in hostile environments. The combination of Cobalt and Chromium also results in an extremely high melting point making them perfect for a range of intriguing applications from extreme cutting tools to hot section alloy coatings in gas turbines. They may also contain molybdenum or tungsten and a small amount of carbon to offer even greater performance for specific applications.
The Stellite range of alloys were first developed by Elwood Haynes in the early 1900s as an alternative for cutlery that was susceptible to staining. Stellite is a trademarked name of the Deloro Stellite Company, now part of the Kennametal group.
Some of the typical applications of Stellite grade 6 are listed below:
- Saw teeth, hardfacing, and acid-resistant machine parts.
- Poppet valves, valve seats and exhaust valves of internal combustion engine.
- M2HB machine gun and machine gun barrels.
- Medical applications including manufacturing of artificial hip joints, other bone replacements and cast structure of dental prosthesis.
- Turning tools for lathes.
