Abstract

MÉTODO PARA PRODUÇÃO DE MATERIAL DE AÇO DE ALTA RESISTÊNCIA EXCELENTE EM RESISTÊNCIA À FRATURA POR ESTRESSE DE SULFETO. Um aço que tem uma composição química consistindo em, em porcento em massa, C: 0,15 a 0,65%, Si: 0,05 a 0,5%, Mn: 0,1 a 1,5%, Cr: 0,2 a 1,5%, Mo: 0,1 a 2,5%, Ti: 0,005 a 0,50%, Al: 0,001 a 0,50%, e opcionalmente pelo menos um elemento selecionado de Nb: (menor igual)0,4%, V: (menor igual)0,5%, e B: (menor igual)0,01%, Ca: (menor igual)0,005%, Mg: (menor igual)0,005%, e REM: (menor igual)0,005%, e o saldo sendo Fe e impurezas, em que Ni, P, S, N e O entre as impurezas são Ni: (menor igual) 0,1%, P: (menor igual) 0,04%, S: (menor igual) 0,01%, N: (menor igual) 0,01%, e O: (menor igual) 0,01%, e que tenha sido trabalhado a quente em uma forma desejada é sequencialmente submetido a uma etapa de aquecer o aço até uma temperatura excedendo o ponto de transformação Ac1 e menor que o ponto de transformação Ac3 e resfriar o aço, a etapa de reaquecer o aço até uma temperatura não inferior ao ponto de transformação Ac3 e resfriar o aço por resfriamento rápido, e uma etapa de temperar o aço a uma temperatura não superior ao ponto de transformação Ac1.
