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.KHR35CW is a further modification of the KHR35C family (see Alloy Digest SS-755) with additions of tungsten and molybdenum to the 25Cr-36Ni content. These modifications are used primarily to further increase the carburization resistance of the alloy.
