Abstract

<B>Patente de Invenção: "CHAPA DE AçO LAMINADA A FRIO COM ALTA RESISTêNCIA E ALTA CONFORMABILIDADE TENDO UM EXCELENTE DESEMPENHO DE ESMAGAMENTO"<D>. A presente invenção refere-se a chapa de aço laminada a frio com alta resistência e alta conformabilidade tendo um excelente desempenho de esmagamento que é na qual a dita chapa de aço contém 0,05-0,40% em massa de C, 1,0-3,0% em massa de Si, 0,6-3,0% e massa de Mn 0,02-1,5% em massa de Cr, 0,010-0,20% em massa de P e 0,01-0,3% em massa de Al enquanto a parte restante consiste substancialmente de Fe; que a dita chapa de aço tem ferrita (ferrita poligonal) como uma fase principal e tem uma fase menor consistindo de martensita, ferrita acicular e austenita retida; que a relação da fase menor na estrutura da chapa até 3-40%; e que as relações de martensita, austenita retida e ferrita acicular na fase menor são 10-80% e 5-60%, respectivamente. De acordo com a presente invenção, é agora possível oferecer chapa de aço laminada a frio com alta resistência e alta conformabilidade tendo um excelente desempenho de esmagamento que não somente exibe uma conformabilidade suficiente principalmente como uma chapa de aço para automóveis mas também é capaz de satisfazer um padrão de segurança severo.
