Stellite

Stellite is an alloy of Co (40-60%), Cr (25-35%), W (4-25%) and C (1-3%). It is a cast alloy containing C, Cr, and W in Cobalt matrix. Its main characteristic is low coefficient of friction and it possesses high hardness, red hardness, high wear and corrosion resistance. Desired size and shape is achieved by casting and no heat treatment is required. They are mainly used for cutting tools and can cut steel at twice the cutting speed of HSS stellite can be used to cut all types of materials like steels, as high speed steels because they are cast but perform better than HSS with higher life.

Satellites are used for cutting hard die faces, can surfaces wear plates and crushes. The hardness varies between 40 to 60 RC and they retain their hardness upto high temperature because they do not undergo phase changes.
