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. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and bend strength as well as fatigue. It also includes information on corrosion resistance as well as forming, machining, and joining. Filing Code: CU-721. Producer or source: Wieland Metals Inc., Wieland-Werke AG.
