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.Kubota KHR35W has additions of tungsten to 25Cr-35Ni base alloy (Alloy digest SS-755). The tungsten is used to further increase carburization resistance in service at temperatures up to 1095 C (2000 F).
