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.Wieland-S23 has good cold-working properties and good strength. However, the alloy undergoes order strengthening (an ordering reaction that increases strength and decrease ductility ) at intermediate temperatures, so that forming should be done first. Applications include springs and connectors.
