To enhance the material's hardness, annealing, normalizing, and quenching methods are employed. It is crucial to cool the Tube T91 in a hydrogen atmosphere to prevent oxidation and maintain its bright surface at high temperatures. Once cooled, the tube is ready for application. The composition of ASTM A213 T91 Tube includes carbon, manganese, phosphorus, sulfur, silicon, molybdenum, and chromium, providing it with a minimum yield strength of 205MPa and a minimum tensile strength of 585MPa. With a maximum hardness of 250 HB, it is exceptionally hard compared to other grades of similar alloys.
