Cobalt alloy 6b / Stellite 6b is a cobalt-based, chromium-tungsten alloy used extensively in wear environments where its low friction coefficient minimises the risk of seizing and galling, even in applications where lubrication is not practical. Stellite 6b is supplied in the solution treated condition (to AMS 5894) and its wear resistant properties inherent in this state limit the amount of heat treating and post machining. Typical applications for Alloy 6b include chain saw guide blades, furnace fan blades, high temperature bearings, valve stems, food processing equipment and steel mill equipment.
