Abstract

La présente invention vise à fournir un tuyau duplex sans soudure en acier inoxydable qui présente une petite différence entre la limite d'élasticité en traction et la limite d'élasticité en compression dans la direction axiale du tuyau, tout en présentant une excellent résistance à la corrosion; et un procédé de production de ce tuyau duplex sans soudure en acier inoxydable. La présente invention concerne par conséquent un tuyau duplex sans soudure en acier inoxydable dont la composition de composants contient, en pourcentage en masse, de 0,005 % à 0,08 % de C, de 0,01 % à 1,0 % de Si, de 0,01 % à 10,0 % de Mn, de 20 % à 35 % de Cr, de 1 % à 15 % de Ni, de 0,5 % à 6,0 % de Mo et 0,005 % ou plus mais moins de 0,150 % de N, le reste étant constitué de Fe et des impuretés inévitables, et qui est conçue de manière à ce que : la limite d'élasticité en traction dans la direction axiale du tuyau est de 689 MPa ou plus; et la valeur de (limite d'élasticité en compression dans la direction axiale du tuyau)/(limite d'élasticité en traction dans la direction axiale du tuyau) est de 0,85 à 1,15.
