Abstract

método para fabricação e utilização de aço inoxidável ferrítico-austenítico com alta formabilidade. a presente invenção está correlacionada a um método de fabricação de um aço inoxidável ferrítico-austenítico, tendo satisfatória formabilidade e alto alogamento. o aço inoxidável é tratado termicamente, de modo que a sua microestrutura contenha 45-75% de austenita na condição tratada termicamente, a microestrutura restante sendo ferrita, e a temperatura medida m~ d30~ do aço inoxidável é ajustada entre 0 e 50<198>c, a fim de utilizar a plasticidade induzida por transformação (trip) para melhorar a formabilidade do aço inoxidável.
