Les mat\u00e9riaux utilis\u00e9s sont l'acier au carbone et l'acier au carbone-mangan\u00e8se. Les tubes et tuyaux ASTM A178 sont principalement utilis\u00e9s pour les tubes de chaudi\u00e8re, les conduits de chaudi\u00e8re, les conduits de surchauffeur et d'autres applications s\u00fbres. Il existe trois nuances d'acier pour l'ASTM A178 : La nuance A (acier \u00e0 faible teneur en carbone), la nuance C (acier \u00e0 teneur moyenne en carbone) et la nuance D (acier au carbone et au mangan\u00e8se). Les processus de fabrication doivent inclure le traitement thermique, le soudage apr\u00e8s refroidissement. Un essai d'\u00e9crasement doit \u00eatre effectu\u00e9 si le client l'exige.<\/p>\n<ul>\n<li>Normes : ASTM A178 Gr.
