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.KHR 35CT is a modification of KHR 35C (see Alloy Digest SS-753) by the addition of titanium as a microalloying improvement. The higher strength obtained allows for more catalyst in reformer furnaces.
