L’acier inoxydable super aust\u00e9nitique W 1.4529 AISI 926 UNS N08926 est similaire au 316L mais avec l’ajout de molybd\u00e8ne, ce qui lui conf\u00e8re une r\u00e9sistance sup\u00e9rieure aux attaques de corrosion localis\u00e9es (corrosion par piq\u00fbres et par crevasses).
\nAvec une valeur PREN comprise entre 41 et 48, il convient aux applications dans l’eau de mer chaude et dans d’autres environnements \u00e0 forte teneur en chlorure. La teneur \u00e9lev\u00e9e en nickel se traduit par une meilleure r\u00e9sistance \u00e0 la corrosion sous contrainte que les nuances aust\u00e9nitiques standard. Le cuivre contenu dans l’alliage renforce la r\u00e9sistance aux acides sulfuriques et aux autres acides r\u00e9ducteurs, en particulier dans la gamme tr\u00e8s agressive des \u00ab\u00a0concentrations moyennes\u00a0\u00bb. Dans la plupart des environnements, l’acier W 1.4529 AISI 926 UNS N08926 pr\u00e9sente une performance de corrosion interm\u00e9diaire entre la nuance aust\u00e9nitique standard 316L et les nuances riches en molybd\u00e8ne (environ 6 %) ou super aust\u00e9nitiques.<\/p>\n

Les normes EN ISO 3506-1 (ins\u00e9rer le lien) et EN 3506-2 (ins\u00e9rer le lien) classent ce mat\u00e9riau comme A8 adapt\u00e9 aux applications structurelles selon DIN-EN 1993-1-4:2015-10\/EUROCODE 3-ANNEX A classes CRC (ins\u00e9rer le lien).<\/p>\n

Il trouve des applications dans les syst\u00e8mes de tuyauterie, les \u00e9quipements de contr\u00f4le de la pollution, les \u00e9changeurs de chaleur et les syst\u00e8mes de blanchiment.<\/p>\n
