Efeito do revenido na resistência à corrosão dos aços inoxidáveis supermartensíticos

Abstract: ResumoOs aços inoxidáveis supermartensíticos são utilizados nas indústrias de petróleo e gás, pois aliam boas propriedades mecânicas, soldabilidade e excelente resistência à corrosão. Eles são endurecidos pelo tratamento térmico de têmpera e, para otimizar suas propriedades mecânicas, são submetidos ao revenimento. Durante o revenimento, ocorre precipitação de fases, que, dependendo dos parâmetros temperatura e tempo, induz alterações indesejadas nas propriedades desses aços. Nesse trabalho, o objetivo foi est… Show more

“…Researches have been developed with martensitic stainless steel groups with carbon content between 0.01 and 0.1%, 11 and 13% of chromium, 2 and 6% of nickel and around 2% of molybdenum, in order to be used in welding processes, mainly in the oil industry for offshore oil production. The released heat during welding process implies in temperatures fluctuation in welding joint that results in microstructural modifications, especially in adjacent weld zones (heat affected zone -HAZ), which, in turn, can affect both mechanical and corrosion properties [1][2][3][4].…”
