Abstract

"PROCESSO DE FABRICAçãO DE CHAPAS DE AçO LAMINADO A QUENTE E A FRIO COM ELEVADA RESISTêNCIA E CHAPA OBTIDA". A invenção refere-se a um processo de fabricação de uma chapa de aço de elevada resistência, laminada a quente, depois laminada a frio, apresentando uma resistência à tração RM superior ou igual a 450 MPa, compreendendo as etapas segundo as quais se lamina a quente um aço de elevada resistência, para se obter uma chapa a quente, depois se lamina a frio essa chapa a quente com uma taxa de redução compreendida entre 10 e 20%, depois se faz com que essa chapa assim laminada sofra um tratamento térmico de restauração a uma temperatura inferior a Ac3, assim como a chapa obtida.
