OBJECTIVE: To develop a method to manufacture austenitic-ferritic stainless steel orthodontic wires (SEW 410 Nr. 14517) using conventional rolling and wiredrawing processes. METHODS: Austenitic-ferritic steel was produced in an induction furnace. Traction trials and microhardness measurements were used to evaluate wire quality. Orthodontic parts were fabricated to assess ductility and malleability. RESULTS AND CONCLUSIONS: Austenitic-ferritic stainless steel wires meet the BS 3507:1976 and ISO 5832-1 norms and have excellent ductility for the fabrication of orthodontic parts with complex folds.
