molybd\u00e8ne<\/a> et de l'alliage nickel-azote 4.5%. Il pr\u00e9sente une r\u00e9sistance \u00e9lev\u00e9e, une bonne r\u00e9sistance aux chocs et une bonne r\u00e9sistance globale et locale \u00e0 la corrosion sous contrainte.<\/p>\nL'acier inoxydable duplex 2205 est un acier inoxydable duplex compos\u00e9 de chrome 22%, de molybd\u00e8ne 3% et d'azote nickel 5-6%. Compar\u00e9 au tuyau en acier inoxydable aust\u00e9nitique, le tuyau en acier 2205 a de meilleures performances en termes de r\u00e9sistance \u00e0 la corrosion par piq\u00fbres et crevasses.<\/p>\n
Usinabilit\u00e9<\/strong><\/p>\nSur les machines \u00e0 grande vitesse, la vitesse d'avance et la vitesse de coupe des tubes 2205 sont les m\u00eames que celles du 316L. Si un couteau carbonis\u00e9 est utilis\u00e9, la vitesse de coupe est r\u00e9duite d'environ 20% par rapport \u00e0 316L, et les performances de la machine et de ses composants jouent ici un r\u00f4le cl\u00e9.<\/p>\n
Soudage du tuyau duplex 2205<\/strong><\/p>\nLe tuyau Duplex 2205 a une bonne soudabilit\u00e9. Son soudage n'est pas difficile, mais sa proc\u00e9dure de soudage doit \u00eatre con\u00e7ue de mani\u00e8re \u00e0 ce qu'apr\u00e8s soudage, elle puisse maintenir un bon \u00e9quilibre de phases et \u00e9viter la pr\u00e9cipitation de phases m\u00e9talliques ou non m\u00e9talliques nocives. Peut \u00eatre soud\u00e9 dans : GTAW (TIG), GMAW (MIG), SMAW (\u00e9lectrode \"b\u00e2ton\"), SAW, FCW et PAW.<\/strong><\/p>\n
