La sp\u00e9cification ASTM A193<\/a> grade B8 ou A320 grade B8 d\u00e9finit les caract\u00e9ristiques techniques des fixations en acier inoxydable adapt\u00e9es \u00e0 une application dans des r\u00e9cipients sous pression et en pr\u00e9sence de temp\u00e9ratures \u00e9lev\u00e9es ou basses (temp\u00e9ratures de service -196\u00b0C \u00e0 800\u00b0C) ; ce type de fixations est largement utilis\u00e9 dans les secteurs de la chimie, de l’exploitation mini\u00e8re et de l’\u00e9nergie. Les sp\u00e9cifications ASME SA 193 B8 SA 320 B8 font \u00e9cho aux sp\u00e9cifications ASTM A193<\/a> B8 A320 B8. 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 (A2-50 A2-70 A2-80). <\/p>\n
