Hastelloy C276 (ASTM A 494, qualit\u00e9 CW12MW)<\/h2>\n\n\n\n

Les vannes d'instrumentation Hastelloy C276 hautes performances ont une r\u00e9sistance sup\u00e9rieure \u00e0 divers acides. Par exemple, les robinets \u00e0 tournant sph\u00e9rique Hastelloy C276 ont la capacit\u00e9 de r\u00e9sister aux acides comme l'acide sulfurique, chlorhydrique, fluorhydrique, nitrique et chromique. Le robinet \u00e0 tournant sph\u00e9rique Hastelloy pr\u00e9sente m\u00eame une bonne r\u00e9sistance \u00e0 la corrosion localis\u00e9e.<\/p>\n\n\n\n

CW12MW est l\u2019ancien alliage Hastelloy C moul\u00e9 d\u2019origine. Sa limite de carbone plus \u00e9lev\u00e9e de 0,12% maximum ainsi que ses niveaux plus \u00e9lev\u00e9s de fer et de tungst\u00e8ne rendent cet alliage inf\u00e9rieur \u00e0 toutes les autres qualit\u00e9s en termes de r\u00e9sistance \u00e0 la corrosion et de ductilit\u00e9. CW12MW n'est pas l'\u00e9quivalent moul\u00e9 de l'UNS N10276.<\/p>\n\n\n\n

CW6M<\/h2>\n\n\n\n

CW6M est le prochain alliage coul\u00e9 Ni-Cr-Mo d\u00e9velopp\u00e9. Il a \u00e9t\u00e9 introduit en 1949, il existe donc une longue et fructueuse histoire pour cet alliage. Bien qu'il ait une limite admissible de carbone et de silicium plus \u00e9lev\u00e9e que les nouveaux types C r\u00e9pertori\u00e9s ci-dessous, il est g\u00e9n\u00e9ralement fabriqu\u00e9 avec des niveaux de carbone et de silicium beaucoup plus faibles, ce qui lui conf\u00e8re une bonne r\u00e9sistance \u00e0 la corrosion aux acides oxydants et r\u00e9ducteurs.<\/p>\n\n\n\n

CW2M<\/h2>\n\n\n\n

CW2M est l'\u00e9quivalent moul\u00e9 de l'UNS N06455 d\u00e9velopp\u00e9 en 1976 pour offrir une meilleure stabilit\u00e9 m\u00e9tallurgique que l'UNS N10276 \u00e0 haute temp\u00e9rature. Un avantage suppl\u00e9mentaire est qu'il s'agit d'une meilleure qualit\u00e9 moul\u00e9e que le CW12MW. Ses performances am\u00e9lior\u00e9es par rapport au CW12MW \u00e9taient le r\u00e9sultat de quantit\u00e9s r\u00e9duites de phases interm\u00e9talliques dans sa microstructure. Ceci a \u00e9t\u00e9 accompli en abaissant ses niveaux de carbone, de silicium, de fer, de chrome et de molybd\u00e8ne et en \u00e9liminant l\u2019ajout de tungst\u00e8ne.<\/p>\n\n\n\n

CX2MW<\/h2>\n\n\n\n

CX2MW est l'\u00e9quivalent moul\u00e9 de UNS N06022. Cet alliage a une teneur en chrome plus \u00e9lev\u00e9e, mais une teneur en molybd\u00e8ne inf\u00e9rieure \u00e0 celle des autres alliages Hastelloy de type C. La teneur plus \u00e9lev\u00e9e en chrome conf\u00e8re \u00e0 cet alliage une meilleure r\u00e9sistance \u00e0 la corrosion dans les environnements oxydants chauds tels que l'eau de Javel et les saumures chlor\u00e9es. Cependant, la teneur plus faible en molybd\u00e8ne sacrifie une certaine r\u00e9sistance aux services r\u00e9ducteurs o\u00f9 ces alliages sont \u00e9galement couramment utilis\u00e9s, par exemple les acides sulfurique et chlorhydrique.<\/p>\n\n\n\n

CX2M<\/h2>\n\n\n\n

CX2M est l'\u00e9quivalent moul\u00e9 de UNS N06059. Il contient un peu plus de chrome et de molybd\u00e8ne que le CX2MW. La teneur plus \u00e9lev\u00e9e en chrome peut offrir une bonne r\u00e9sistance aux services oxydants puissants et sa teneur plus \u00e9lev\u00e9e en molybd\u00e8ne peut offrir une bonne r\u00e9sistance aux acides sulfurique et chlorhydrique.<\/p>\n\n\n\n

UNS N06200<\/h2>\n\n\n\n

UNS N06200 (Hastelloy C-2000) est le plus r\u00e9cent alliage de type C, mais il n'est disponible que sous forme de composant corroy\u00e9 car sa teneur extr\u00eamement faible en carbone et en silicium signifie qu'il n'est pas avantageux pour la fabrication d'un alliage coul\u00e9. UNS N06200 contient une teneur en chrome similaire \u00e0 UNS N06022, mais il contient plus de molybd\u00e8ne ainsi qu'une petite quantit\u00e9 de cuivre. La teneur plus \u00e9lev\u00e9e en molybd\u00e8ne et en cuivre conf\u00e8re \u00e0 l'alliage une meilleure r\u00e9sistance aux acides r\u00e9ducteurs comme le sulfurique et le chlorhydrique.<\/p>\n\n\n\n\n
