            \n
          • La r\u00e9sistance \u00e0 la corrosion de l'alliage 17-4PH est meilleure que celle de toute autre plaque d'acier inoxydable trempable standard. Dans la plupart des cas, sa r\u00e9sistance \u00e0 la corrosion n'est pas inf\u00e9rieure \u00e0 celle de 304.<\/li>\n
          • S'il existe un risque de fissuration par corrosion sous contrainte, la temp\u00e9rature de vieillissement la plus \u00e9lev\u00e9e doit \u00eatre sup\u00e9rieure \u00e0 550\u00b0C (1022\u00b0F), de pr\u00e9f\u00e9rence \u00e0 590\u00b0C (1094\u00b0F).<\/li>\n
          • La temp\u00e9rature de trempe dans le milieu chlorure est de 550\u00b0C-1022\u00b0F.<\/li>\n
          • La temp\u00e9rature de trempe en milieu H2S est de 590\u00b0C-1094\u00b0F.<\/li>\n
          • Il est sensible \u00e0 la corrosion ou \u00e0 la corrosion fissurante dans l'eau de mer statique.<\/li>\n
          • Sa r\u00e9sistance \u00e0 la corrosion est la m\u00eame que celle de la nuance 304L dans les industries p\u00e9trochimique, alimentaire et papeti\u00e8re.<\/li>\n<\/ul>\n
