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%.<B> METHOD FOR MANUFACTURING A STAINLESS STEEL STRIP <D> ". A method for fabricating a stainless steel strip, particularly a austenitic stainless steel strip, with the desired final thickness and deformation force of at least 250 N / mm ^ 2 ^, includes the continuous casting of a stainless steel, particularly austenitic stainless steel, into a strip having a thickness of at least 1 mm and a maximum of 10 mm, optionally hot lamination of the molten strip, cooling of said molten strip and optionally hot rolled to room temperature, cold rolled from said molten strip and optionally hot rolled with at least a 10% thickness reduction to a thickness which is at least 2% and a maximum of 20%, preferably a maximum of 10 % greater than the desired final thickness of the finished product, annealing the strip thus cold rolled at a temperature between 1,050 ‹C and 1,250‹ C, and working outside the strip after said annealing process in order to lengthen permanently increase the strip and thereby reduce its thickness by 2-20%, preferably 2-10%.
