Product Description

Stellite is a cobalt-based cemented carbide that is resistant to various types of wear and corrosion, as well as high-temperature oxidation. Invented in 1907 by American Elwood Haynes. Stellite alloys are mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten and a small amount of alloying elements such as molybdenum, niobium, tantalum, titanium, lanthanum, and occasionally iron. Our company adopts powder metallurgy, casting, forging, welding and other processes to ensure the excellent performance of materials. Among them, the powder metallurgy technology is particularly mature, the product performance is stable, the precision is high, and mass production can be carried out. Stellite alloys are suitable for conditions that require both high-temperature resistance, wear resistance and corrosion resistance. The more complex the working conditions are, the more the advantages of Stellite alloys can be reflected.
