Abstract

<B>MéTODO PARA FABRICAR UMA TIRA DE AçO INOX<D>". Um método para fabricar uma tira de aço inox, particularmente uma tira de aço inox austenítico, com desejada espessura final e força de deformação de ao menos 250 N/mm^ 2^, inclui a fundição contínua de um aço inox, particularmente um aço inox austenítico, em uma tira possuindo uma espessura de ao menos 1 mm e no máximo 10 mm, opcionalmente laminação à quente da tira fundida, resfriamento da dita tira fundida e opcionalmente laminado à quente para a temperatura ambiente, laminação a frio da dita tira fundida e opcionalmente laminado à quente com ao menos uma redução de espessura de 10% para uma espessura a qual é ao menos 2% e no máximo 20%, preferivelmente no máximo 10% maior do que a espessura final desejada do produto acabado, recozimento da tira assim laminado a frio em uma temperatura entre 1.050‹C e 1.250‹C, e trabalho a fro da tira após o dito processo de recozimento de maneira a alongar permanentemente a tira e com isso reduzir sua espessura em 2-20%, preferivelmente em 2-10%.
