Cobalt-based Stellite™ Alloys
The cobalt-based Stellite™ Alloys are the most well-known and successful alloys in the world, with the best “all-round” properties. They combine excellent mechanical wear resistance, especially at high temperatures, with very good corrosion resistance.
The Right Tool for the Job
The Stellite alloys are mostly cobalt based with additions of Cr, C, W, and/or Mo. They are resistant to cavitation, corrosion, erosion, abrasion, and galling. The lower carbon alloys are generally recommended for cavitation, sliding wear, or moderate galling. The higher carbon alloys are usually selected for abrasion, severe galling, or low- angle erosion. Stellite 6 is our most popular alloy as it provides a good balance of all of these properties.
The Stellite alloys retain their properties at high temperatures where they also have excellent oxidation resistance. They are typically used in the temperature range 315 – 600° C (600 – 1112° F). They can be finished to exceptional levels of surface finish with a low coefficient of friction to give good sliding wear.
