La sp\u00e9cification ASTM A193<\/a> grade B8M ou A320 grade B8M d\u00e9finit les caract\u00e9ristiques techniques des fixations en acier inoxydable pour les applications de cuves sous pression \u00e0 haute temp\u00e9rature (temp\u00e9ratures de service -196\u00b0C – 800\u00b0C) ; ce type de fixations est largement utilis\u00e9 dans les secteurs du p\u00e9trole, des mines et des usines chimiques \u00e9nerg\u00e9tiques.<\/p>\n

Les sp\u00e9cifications de l’ASME SA 193 B8M rappellent celles de l’ASTM A193<\/a> B8M. Ce mat\u00e9riau convient \u00e0 la fabrication de composants conformes aux normes EN ISO 3506-1 et EN ISO 3506-2 dans les diff\u00e9rentes caract\u00e9ristiques de r\u00e9sistance m\u00e9canique en fonction de l’\u00e9tat de la pi\u00e8ce finie (A4-50, A4-70 et A4-80).<\/p>\n
