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.Datalloy 2 is an enhanced corrosion-resistant nonmagnetic stainless steel. The composition contains a high level of manganese and nitrogen to stabilize the austenite. Applications include replacement of standard chromium-manganese steels in drill string components.
