Tuyau Duplex<\/a> est soutenu par de l'acier inoxydable duplex, il comporte donc de l'acier inoxydable duplex.<\/h2>\n

L'acier inoxydable duplex a les caract\u00e9ristiques de performance suivantes :<\/strong>
\n(1) L'acier inoxydable duplex contenant du molybd\u00e8ne pr\u00e9sente une bonne r\u00e9sistance \u00e0 la corrosion sous contrainte par le chlorure sous faible contrainte. En g\u00e9n\u00e9ral, l'acier inoxydable aust\u00e9nitique de type 18-8 est sujet \u00e0 la corrosion sous contrainte par le chlorure. fissuration par corrosion sous contrainte<\/a> dans une solution de chlorure neutre \u00e0 plus de 60 \u00b0C, ainsi que les \u00e9changeurs de chaleur, les \u00e9vaporateurs, etc. fabriqu\u00e9s dans cet acier inoxydable dans un milieu industriel contenant des traces de chlorure et de sulfure d'hydrog\u00e8ne. L'acier inoxydable duplex pr\u00e9sente une bonne r\u00e9sistance \u00e0 la corrosion sous contrainte, alors qu'il a tendance \u00e0 se fissurer.<\/p>\n

(2) L'acier inoxydable duplex contenant du molybd\u00e8ne a une bonne r\u00e9sistance aux piq\u00fbres. Le potentiel de piq\u00fbre duplex de l'acier inoxydable duplex est similaire \u00e0 celui de l'acier inoxydable aust\u00e9nitique lorsqu'il a la m\u00eame valeur \u00e9quivalente de r\u00e9sistance aux piq\u00fbres (PRE=Cr%+3.3Mo%+16N%). La r\u00e9sistance \u00e0 la corrosion par piq\u00fbres de l'acier inoxydable duplex et de l'acier inoxydable aust\u00e9nitique est comparable \u00e0 celle de l'AISI 316L. La r\u00e9sistance \u00e0 la corrosion par piq\u00fbres et crevasses des aciers inoxydables duplex \u00e0 haute teneur en chrome contenant du 25% Cr, en particulier de l'azote, d\u00e9passe celle de l'AISI 316L.<\/p>\n

(3) Il a une bonne r\u00e9sistance \u00e0 la corrosion et \u00e0 la corrosion. Il convient \u00e0 la fabrication d'\u00e9quipements \u00e9lectriques tels que des pompes et des vannes dans certaines conditions de fluides corrosifs.<\/p>\n

(4) Les propri\u00e9t\u00e9s m\u00e9caniques globales sont bonnes. Il a une r\u00e9sistance \u00e9lev\u00e9e et une r\u00e9sistance \u00e0 la fatigue, et sa limite d'\u00e9lasticit\u00e9 est le double de celle de l'acier inoxydable aust\u00e9nitique 18-8. L'allongement \u00e0 l'\u00e9tat de solution solide est de 25% et la valeur de t\u00e9nacit\u00e9 AK (entaille en V) est sup\u00e9rieure \u00e0 100J.<\/p>\n

(5) Bonne soudabilit\u00e9, faible tendance \u00e0 la fissuration thermique, g\u00e9n\u00e9ralement pas de pr\u00e9chauffage avant soudage, pas de traitement thermique apr\u00e8s soudage, et peut \u00eatre soud\u00e9 avec de l'acier inoxydable aust\u00e9nitique de type 18-8 ou de l'acier au carbone.<\/p>\n

(6) La temp\u00e9rature de traitement duplex de l'acier inoxydable duplex \u00e0 faible teneur en chrome (18%Cr) est plus large que celle de l'acier inoxydable aust\u00e9nitique 18-8, et la r\u00e9sistance est faible, et la t\u00f4le d'acier peut \u00eatre directement lamin\u00e9e et lamin\u00e9e sans forgeage. Le traitement \u00e0 chaud de l'acier inoxydable duplex \u00e0 haute teneur en chrome (25% Cr) est un peu plus difficile que l'acier inoxydable aust\u00e9nitique, et peut produire des produits tels que des plaques, des tubes et des fils.<\/p>\n

(7) Compar\u00e9 \u00e0 l'acier inoxydable aust\u00e9nitique de type 18-8, l'effet d'\u00e9crouissage est plus important dans le travail \u00e0 froid. Lorsque le tube et la plaque sont soumis \u00e0 une d\u00e9formation, une contrainte importante est n\u00e9cessaire pour se d\u00e9former.<\/p>\n

(8) Par rapport \u00e0 l'acier inoxydable aust\u00e9nitique, il a une grande conductivit\u00e9 thermique et un faible coefficient de dilatation lin\u00e9aire, et convient pour une utilisation comme rev\u00eatement d'\u00e9quipement et pour la production de panneaux composites. Convient \u00e9galement \u00e0 la fabrication de matrices d'\u00e9changeur de chaleur, l'efficacit\u00e9 du transfert de chaleur est sup\u00e9rieure \u00e0 celle de l'acier inoxydable aust\u00e9nitique.<\/p>\n

(9) Il existe encore diverses tendances \u00e0 la fragilit\u00e9 de l'acier inoxydable ferritique \u00e0 haute teneur en chrome, qui ne devraient pas \u00eatre utilis\u00e9s dans des conditions de travail sup\u00e9rieures \u00e0 300 \u00b0C. Plus la teneur en chrome de l'acier inoxydable duplex est faible, moins la phase fragile telle que \u03c3 est nocive.<\/p>","protected":false},"featured_media":5095,"template":"","categories":[186],"tags":[],"class_list":["post-5261","blog","type-blog","status-publish","has-post-thumbnail","hentry","category-stainless-steel-knowledge"],"yoast_head":"\nPerformance Characteristics Of Duplex Stainless Steel Pipe -
