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.Nirosta 4000 is a common ferritic stainless steel. Like all 13% Cr steels, the corrosion resistance lies at the lower durability limit for stainless steels. The alloy therefore offers resistance only to dilute acids, water, and steam. The alloy possesses a higher resistance to corrosion when highly polished or precision ground. It is used principally as apparatus for the mineral oil industry.
