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 alloy KHR20T is an iron-chromium-nickel cast alloy with microalloying additions that increase its strength to greater than that of HK40 from 871-982 C (1600-1800 F).
