Abstract

resumo da patente de invenção para: "produto plano de aço laminado a frio para aplicações de estampagem e método para a sua produção". a invenção diz respeito a um produto plano de aço laminado a frio para aplicações de estampagem feito a partir de um aço que, para além de fe e de impurezas inevitáveis, contém (em % em peso) c: 0,008% - 0,1%, al: 6,5% - 12%, nb: 0,1% - 0,2%, ti: 0,15% - 0,5%, p: < 0,1%, s: < 0,03%, n: < 0,1%, e, facultativamente, um ou mais elementos do conjunto "mn, si, rem, mo, cr, zr, v, w, co, ni, b, cu, ca, n", desde que mn: < 1%, rem: < 0,2%, si: < 2%, zr: < 1%, v: < 1%, w: < 1%, mo: < 1%, cr: < 3%, co: < 1 %, ni: < 2%, b: < 0,1%, cu: < 3%, ca: < 0,015%. os valores seguintes aplicam-se à razão % de ti/% de nb, em que % de ti = fração de ti e % de nb = fração de nb: 2,5 > % de ti/% de nb = 1,5. para se produzir tal produto plano de aço, aplica-se a um molde um aço com uma composição correspondente para se obter um pré-produto, o qual é então laminado a quente a uma temperatura final de laminagem a quente de 820ºc - 1000ºc. a banda laminada a quente é então enrolada a uma temperatura de enrolamento até 750ºc, é recozida a uma temperatura de recozimento > 650ºc - 1200ºc ao longo de 1 a 50 horas após o enrolamento, depois é laminada a frio para se obter o produto plano de aço laminado a frio até um grau total de laminagem a frio = 65% em uma ou mais etapas e, por último, é submetida a um recozimento final a 650ºc - 850ºc.
