      Stellite 20

      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 20 is one of the most abrasion-resistant standard cobalt-base alloys. It also has good corrosion resistance. While it has low shock resistance, it is often the only answer for some environments where chemical resistance, in addition to abrasion resistance, is required.

      Stellite 20 has been used in slurry pumps, pump sleeves, rotary seal rings, wear pads and bearing sleeves. 

      Available Product Forms

      Stellite 20 is available as a casting, powder metallurgy components, rod and powder.
