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(UNS R30016) 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.
Cobalt Chromium alloys are non-magnetic and typically associated with high corrosion resistance and as with many alloys, they are adaptable and can be refined for a range of specific applications. Due to their incredibly hard material properties, Alloys 6 and Stellite 6B (UNS R30016) are inherently difficult and often expensive to machine, therefore some very precise casting and grinding methods are often employed.
We have Cobalt Alloy 6b / Stellite 6b is available in round bar, wire, sheet and plate. For all stock availability contact us: daisy@lorkgroup.com.
