Beaucoup pensent que l’utilisation de l’AISI 304 ou de l’AISI 316 peut r\u00e9soudre tous les probl\u00e8mes de rouille des vis, mais ce n’est pas vrai. Pour les applications en eau de mer, les fixations standard en acier inoxydable ne garantissent pas des syst\u00e8mes de fixation durables pour tous vos \u00e9quipements, car m\u00eame ces familles d’aciers inoxydables peuvent \u00eatre affect\u00e9es par la rouille. <\/p>\n

Les ions chlorure peuvent provoquer des attaques corrosives localis\u00e9es (piq\u00fbres et corrosion interstitielle) des aciers inoxydables sensibles. Dans un environnement d’eau de mer, il faut clarifier si l’acier inoxydable est immerg\u00e9, ou situ\u00e9 au bord de la mer de mani\u00e8re \u00e0 \u00eatre attaqu\u00e9 par le chlorure pr\u00e9sent dans l’eau de mer via des \u00e9claboussures ou transport\u00e9 par la brise marine. <\/p>\n

Lorsque l’acier inoxydable est immerg\u00e9, un nombre \u00e9quivalent de r\u00e9sistance \u00e0 la piq\u00fbre (PREN) sup\u00e9rieur \u00e0 40 est g\u00e9n\u00e9ralement sp\u00e9cifi\u00e9 comme minimum pour la r\u00e9sistance \u00e0 l’eau de mer. Les aciers inoxydables, tels que les aciers inoxydables super aust\u00e9nitiques (par exemple UNS S31254 ou 904L) ou les aciers inoxydables super duplex (par exemple UNS S32760 ou S32750<\/a>), r\u00e9pondent \u00e0 cette exigence. <\/p>\n

Pour \u00e9viter le probl\u00e8me de la rouille, la meilleure et la plus \u00e9conomique solution est d’adopter des vis en acier inoxydable duplex, le juste compromis entre prix et performance.<\/p>\n","protected":false},"excerpt":{"rendered":"
