Abstract

TUBO SEM COSTURA DE AÇO INOXIDÁVEL E MÉTODO PARA FABRICAR O MESMO. Um objeto da presente invenção é fornecer um tubo sem costura de aço inoxidável tendo excelente resistência à corrosão e tendo uma pequena diferença entre seu limite de escoamento à tração axial e limite de escoamento à compressão axial. A invenção também se destina a fornecer um método para a fabricação de tal tubo sem costura de aço inoxidável. É fornecido um tubo sem costura de aço inoxidável que é um aço inoxidável compreendendo, em % em massa, Cr: 11,5 a 35,0%, e Mo: 0,5 a 6,0%, e incluindo ferrita e austenita, o tubo sem costura de aço inoxidável com um contorno de grão de ferrita e/ou um contorno de grão de ferrita-austenita com uma concentração de Mo (% em massa) que é no máximo 4,0 vezes a concentração de Mo intragranular (% em massa) de ferrita, ou um contorno de grão de austenita com a concentração de Mo (% em massa) que é no máximo 4,0 vezes a concentração de Mo intragranular (% em massa) de austenita, o tubo sem costura de aço inoxidável com um limite de escoamento à tração axial de 689 MPa ou mais e uma relação de limite de escoamento à compressão axial/limite de escoamento à tração axial de 0,85 a 1,15.
