1. Introduction au mat\u00e9riel GH3030<\/span><\/strong><\/p>\n

L'alliage haute temp\u00e9rature GH3030 renforc\u00e9 par une solution solide est un alliage haute temp\u00e9rature renforc\u00e9 par une solution solide 80Ni-20Cr d\u00e9velopp\u00e9 tr\u00e8s t\u00f4t. Il a une composition chimique simple et a une r\u00e9sistance thermique satisfaisante et une plasticit\u00e9 \u00e9lev\u00e9e en dessous de 800\u2103. Il a \u00e9galement de bonnes performances en mati\u00e8re d'antioxydant, de fatigue thermique, d'emboutissage \u00e0 froid et de processus de soudage. Apr\u00e8s le traitement de solution solide, l'alliage est aust\u00e9nite monophas\u00e9, et la structure est stable pendant l'utilisation. Les principaux produits sont des plaques minces lamin\u00e9es \u00e0 froid, qui peuvent \u00e9galement fournir des produits d\u00e9form\u00e9s tels que des barres, des anneaux, des fils et des tuyaux. Principalement utilis\u00e9 pour les composants de la chambre de combustion des moteurs \u00e0 turbine qui fonctionnent \u00e0 moins de 800\u00b0C et d'autres composants \u00e0 haute temp\u00e9rature qui n\u00e9cessitent une r\u00e9sistance \u00e0 l'oxydation inf\u00e9rieure \u00e0 1100\u00b0C mais qui supportent de tr\u00e8s faibles charges. [Le GH3030 poss\u00e8de d'excellentes propri\u00e9t\u00e9s de traitement \u00e0 chaud et \u00e0 froid, et est utilis\u00e9 pour fabriquer divers \u00e9quipements chimiques et accessoires connexes.<\/span><\/p>\n
