Stellite

This is an alloy of Co as 40-60%, Cr as 25-35%, W as 4-25% and C as 1-3%. This is a cast alloy comprising C, W, and Cr in Cobalt matrix. Its major characteristic is low coefficient of friction and this possesses high hardness, high wear, corrosion resistance and red hardness. Desired shape and size is achieved via casting and no heat treatment is essential. They are mainly utilization for cutting tools and can cut steel at double the cutting speed of HSS stellite can be utilized to cut all types of materials like steels, as elevated speed steels since they are cast but perform better than HSS along with higher life.

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