Abstract

"AçO PARA FORMAS DE MATERIAL PLáSTICO E PROCESSO PARA O TRATAMENTO TéRMICO DAS MESMAS". A invenção refere-se a um aço endurecível com martensita com capacidade de levantamento de aparas aperfeiçoada, boa capacidade de solda e alta resistência à corrosão, um processo para o tratamento térmico de um tal aço, bem como seu emprego. De acordo com a invenção, este aço contém (em %, em peso) 0,02 - 0,075 % de carbono 0,1 - 0,6 % de silício 0,5 - 0,9 % de manganês 0,08 - 0,25 % de enxofre no máximo 0,04 % de fósforo 12.4 - 15,2 % de cromo 0,05 - 1,0 % de molibdênio 0,2 - 1,8 % de níquel no máximo 0,15 % de vanádio 0,1 - 0,45 % de cobre no máximo 0,03 % de alumínio 0,02 - 0,08 % de nitrogênio, bem como eventualmente um ou vários outros elementos de liga até o máximo de 2,0 %, restante ferro e impurezas condicionadas pela preparação e possui uma quota de ferrita na estrutura de menos do que 28 %, em volume. Um processo para o tratamento térmico de um aço endurecível com martensita com capacidade de levantamento de aparas aperfeiçoada, cujo processo prepara um objeto temperado também em grande corte transversal, constitui-se essencialmente no fato, de que um bloco de aço com a composição acima é submetido em uma primeira etapa a um tratamento de calcinação para a formação e ajuste de uma quota de ferrita na estrutura e em uma segunda etapa é efetuada uma deformação térmica do mesmo, depois do que em uma terceira etapa é efetuada uma calcinação macia e, em seguida, um melhoramento térmico.
