Abstract | High strength stainless steel piping which contains as mass%, C =0.05%, Si = 1.0%, P = 0.05%, S <0.002%, Cr >16% and =18%, Mo >2% and = 3%, Cu 1%-3.5%, Ni =3% and <5%, Al 0.001%-0.1% and O =0.01%, and also Mn =1% and N in the region of =0.05%, where Mn and N satisfy equation (1), with the remainder comprising Fe and impurities, wherein the metal structure is mainly a martensite phase, with a ferrite phase of 10-40% v/v and a residual ? phase of =10% v/v. This high strength stainless steel piping has adequate corrosion resistance in an environment of high temperature carbon dioxide and has outstanding resistance to sulphide stress cracking at normal temperatures [Mn] x ([N] - 0.0045) =0.001 (1) where the symbols for the elements in equation (1) represent the quantities of each element in the steel (units: mass%).
La présente invention concerne un tuyau en acier inoxydable à haute limite élastique qui contient, en % en masse, C = 0,05 %, Si = 1,0 %, P = 0,05 %, S < 0,002 %, Cr > 16 % et = 18 %, Mo > 2 % et = 3 %, Cu 1 % - 3,5 %, Ni = 3 % et < 5 %, Al 0,001 % - 0,1 %, O = 0,01 %, Mn = 1 % et N de l'ordre de = 0,05 %, Mn et N satisfaisant l'équation (1), le reste comprenant du Fe et des impuretés. La structure métallique est principalement une phase de martensite, avec une phase de ferrite de 10 - 40 % v/v et une phase ? résiduelle = 10 % v/v. Ce tuyau en acier inoxydable à haute limite élastique présente une résistance à la corrosion appropriée dans un environnement contenant du dioxyde de carbone à haute température et une résistance élevée à la corrosion fissurante en présence d'hydrogène sulfuré à des températures normales. [Mn] x ([N] - 0,0045) = 0,001 (1) où les symboles des éléments dans l'équation (1) représentent les quantités de chaque élément dans l'acier (unités : % en masse). |
