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 KHR48N HiSi is a Ni-Cr-Fe alloy with a 5% W addition. The alloy was designed for high-temperature operating parameters of strength, good carburization resistance, and high oxidation resistance. It is a modification of KHR48N (see Alloy Digest Ni-582) adjusted in composition to maximize carburization resistance.
