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. Tensile tests and microhardness measurements were used to evaluate the wires quality. Orthodontic components were fabricated to assess ductility and malleability. Results and Conclusions: Austenitic-ferritic stainless steel wires meet the BS 3507:1976 and ISO 5832-1 standards and have excellent ductility for the fabrication of orthodontic parts with complex folds.
