What is ASTM A209 T1, T1a, T1b Seamless Alloy Steel Tubes?
ASTM A209 /A209M covers several grades of minimum- wall-thickness, seamless, carbon-molybdenum alloy-steel, boiler and superheater tubes. ASTM A209 T1, T1a, and T1b are Molybdenum Alloy Steel Tubes designed for high-temperature boiler applications. These tubes offer excellent strength, heat resistance, and corrosion resistance, making them ideal for use in boilers, heat exchangers and power plants. ASTM A209 /A209M ASME SA209 tubes shall be made by the seamless process and shall be either hot finished or cold finished as specified. The steel shall be killed.
Heat Treatment And Manufacturing Process Of ASTM A209 T1, T1a, T1b Seamless Alloy Steel Tubes
ASME SA209, ASTM A209/A209M seamless tubes shall be made by the seamless process and shall be either hot finished or cold finished as specified. The steel shall be killed. Hot-finished tubes shall be heat treated at a temperature of 1200°F [650°C] or higher. Cold- finished tubes shall, after the final cold finishing, be heat treated at a temperature of 1200°F [650°C] or higher, or tubing may be furnished in the full-annealed, isothermal annealed or normalized and tempered condition. If furnished in the normalized and tempered condition, the minimum tempering temperature shall be 1200°F [650°C].
