Stellites are cobalt-based alloys whose advantages over steels are their thermal and chemical resistance in a temperature range up to 800°C. Due to a variable share of hard particles it is possible to achieve a tailored wear resistance.

Furthermore the powder metallurgical production process creates a structural homogeneousness which enhances the distribution of hard particles and the isotropy of the structural components.

The resistance to the oxidation at elevated temperatures and the improved resistance in an aggressive environment as well as the high wear resistance are definite advantages over steels thus opening up sophisticated fields of industrial applications
