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 KHR12C is an austenitic Fe-Cr-Ni-Nb casting alloy developed from the well known HH type II grade. This alloy is superior to other grades in components that are subjected to frequent thermal cycling and shock. The alloy is available in both centrifugal and static castings.
