Stellite® 6 is a cobalt based alloy that consists of complex carbides in an alloy matrix. As discussed, cobalt is resistant to wear, galling and corrosion at high temperatures. Stellite® 6 is the most widely used of wear resistant cobalt-based alloys and exhibits good performance. It is industry standard for general purpose wear resistance applications, and has excellent resistance to many forms of mechanical and chemical degradation. This material also remains at a high level of hardness up to 500C. It has good resistance to impact and cavitation erosion. Stellite® 6 is used in a variety of hardfacing processes and can be used with carbide tooling.
