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 HL is an austenitic Fe-Cr-Ni heat-resistant stainless steel casting with similar properties to those of HK 40. The higher chromium in the alloy confers better resistance to scaling by oxidizing and sulfur-bearing gases, while also increasing, the resistance to carburization.
