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.URANUS B6 is a high-alloy austenitic stainless steel with low carbon content. It was originally developed and used for many years to resist corrosion in dilute sulfuric acid. It is one of the best stainless steels for very aggressive chemical environments, in particular sulfuric and phosphoric acids.
