Abstract

"PROCESSO PARA A PRODUçãO DE AçOS INOXIDáVEIS COM MELHOR RESISTêNCIA à CORROSãO". Processo para a produção de um aço inoxidável com melhor resistência à corrosão, que inclui a homogeneização de pelo menos uma parte de um artigo de aço inoxidável incluindo cromo, níquel e molibdênio e com um PRE~ N~ de pelo menos 50, conforme calculado pela equação: PRE~ N~ = Cr + (3,3 x Mo) + (30 x N), em que Cr é a porcentagem em peso de cromo, Mo é a porcentagem em peso de molibdênio, e N é a porcentagem em peso de nitrogênio no aço. Em uma forma do processo, pelo menos uma parte do artigo é refundida para homogeneizar a parte. Em outra forma do processo, o artigo é recozido sob condições suficientes para homogeneizar pelo menos uma região de superfície do artigo. O processo da invenção aumenta a resistência à corrosão do aço inoxidável conforme refletido pela temperatura crítica de corrosão em fissura do aço.
