View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.HAYNES STELLITE alloy No. 6K is a cobalt-base alloy with outstanding resistance to most types of wear. Its wear resistance is a built-in characteristic and not the result of heat-treatment, plating, nitriding, or other methods used to produce a superficial hardness on metal parts. Among its many applications are cutting knives and blades for many materials, apple-paring knives in canneries and wear strips in conveyor channels.
