    ASTM A335 T11 Seamless Alloy Steel Pipe for High-Temperature Service


    ASTM A 335 Gr. T11 Seamless Alloy Steel Pipe | High-Temperature Pressure Pipe | YUHONG



    1. Product Overview: High-Temperature Performance


    ASTM A335 T11 pipes are 1.25Cr-0.Mo seamless pipes designed for critical applications requiring exceptional heat resistance. Manufactured to meet ASTM A335/A335M-2024 standards, these pipes deliver superior creep strength at temperatures up to 650°C (1200°F). Ideal for power plants and refining processes with service pressures exceeding 20 MPa.
