Qu'est-ce qu'un tuyau sans soudure en acier inoxydable aust\u00e9nitique<\/h2>\n

aust\u00e9nitique tuyau sans soudure en acier inoxydable<\/a> fait r\u00e9f\u00e9rence \u00e0 un tuyau en acier inoxydable<\/a> avec structure aust\u00e9nitique sous haute temp\u00e9rature et temp\u00e9rature normale.<\/p>\n

\"tuyaux<\/a><\/p>\n

Lorsque le tube en acier contient environ 18% de Cr, 8% \u00e0 10% de Ni et environ 0,1% de C, il a une structure aust\u00e9nite stable.<\/p>\n

Les aciers inoxydables aust\u00e9nitiques au chrome-nickel comprennent les aciers bien connus 18Cr-8Ni et les aciers \u00e0 haute teneur en Cr-Ni d\u00e9velopp\u00e9s en augmentant la teneur en Cr et Ni et en ajoutant des \u00e9l\u00e9ments tels que Mo, Cu, Si, Nb et Ti.<\/p>\n

L'acier inoxydable aust\u00e9nitique est non magn\u00e9tique et a une t\u00e9nacit\u00e9 et une plasticit\u00e9 \u00e9lev\u00e9es, mais sa r\u00e9sistance est faible. Il ne peut pas \u00eatre renforc\u00e9 par une transformation de phase. Il ne peut \u00eatre renforc\u00e9 que par un travail \u00e0 froid. Si S, Ca, Se, Te et d'autres \u00e9l\u00e9ments sont ajout\u00e9s, il a une bonne usinabilit\u00e9.<\/p>\n
