“…Studies have reported that the two characteristics of alloy and the manufacturing process are the main factors influencing the corrosion of brackets. These data guided the selection of brackets used in this study, which compared stainless steel AISI 316L, the main alloy employed for fabrication of orthodontic brackets, 14 by two manufacturing processes, one piece (group C, Dentaurum) and combined or multiparts (group B, American Orthodon-tics) and brackets fabricated with the AISI 303 alloy in one piece (group A, 3M UNITEK). Combination of these three groups allowed isolated comparison between the types of alloy, 316L and 303, and the manufacturing process in a one piece or multipart technique (brazing).…”

“…This alloy's microstructure is composed of a mixture of austenitic and delta-ferritic phases [24,25]. Chromium content is high (18% to 26%) and nickel content is low (4% to 7%).…”

“…Duplex stainless steels have high weldability, higher tensile and yield strengths than austenitic or ferritic stainless steels, high toughness [24,26], are harder than austenitic types and more ductile than ferritic ones and, due to the presence of the austenitic phase, its corrosion resistance is good [25]. In fact, duplex alloys show better resistance to intergranular corrosion and uniform corrosion than austenitic types [22].…”

“…A combinação entre os elevados valores de alongamento da austenita com o elevado limite de escoamento da ferrita nos aços inoxidáveis duplex formam um conjunto de notáveis propriedades mecânicas, chegando a alongamento mínimo de 25% e dureza de 260 HV [1]. O percentual de ferrita aumenta o nível de microdureza para diferenças significativas na relação austenita/ferrita, sendo a ferrita uma microestrutura mais dura e a austenita mais macia e dúctil [5,6,7].…”
