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.UNILOY HC is a corrosion and heat resisting solid solution strengthened alloy. The alloy combines excellent high temperature properties up to 1800 F with exceptional resistance to both oxidizing and reducing atmospheres to 2000 F. It is used in a variety of aggresive environments for chemical processing equipment, reaction vessels, valves and jet engine afterburner cones.
