Stellite 6

Stellite 6 is the most widely used of the wear resistant cobalt-based alloys and exhibits good all-round performance






Cobalt based alloy/stellite alloy is a range of cobalt-chromium-tungsten alloys designed for wear resistance, corrosion resistance and high termal resistance. It has excellent wear and corrosion resistance performance at relatively high temperature. It is widely used in oil&gas, metallurgy, machinery, wood cutting, automotive, paper and food processing industries etc.
