1. Introduction aux mat\u00e9riaux Monel400<\/span><\/strong>
\nLe Monel 400 est un alliage r\u00e9sistant \u00e0 la corrosion dont l'utilisation est vaste et \u00e9tendue et dont les performances globales sont excellentes. Cet alliage pr\u00e9sente une excellente r\u00e9sistance \u00e0 la corrosion dans l'acide fluorhydrique et les gaz fluor\u00e9s, ainsi qu'une excellente r\u00e9sistance \u00e0 la corrosion dans les liquides alcalins concentr\u00e9s chauds. Les mat\u00e9riaux en alliage \u00e0 base de nickel pr\u00e9sentent une bonne r\u00e9sistance \u00e0 la corrosion dans l'eau de mer, les solutions neutres, les solvants chimiques, le chlorure de sulfhydryle d'ammoniac, le chlorure d'hydrog\u00e8ne, divers milieux acides tels que l'acide sulfurique, l'acide fluorhydrique, l'acide chlorhydrique, l'acide phosphorique, l'acide organique, les milieux alcalins, les sels et les sels fondus.<\/span><\/p>\n

Une caract\u00e9ristique importante de cet alliage est qu'il ne produit g\u00e9n\u00e9ralement pas de fissures de corrosion sous contrainte et qu'il pr\u00e9sente de bonnes performances de coupe. La structure de l'alliage Monelhe 400 est une solution solide monophas\u00e9e \u00e0 haute r\u00e9sistance.<\/span><\/p>\n
