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.KHR35H is a high-temperature heat resistant alloy with a molybdenum addition to increase creep and rupture strength to levels better than those of HP alloy. Typical applications are in heat treatment equipment.
