ASTM A376 TP347H Stainless Steel Seamless Pipe for High-Temperature
ASTM A376 is a standard developed by the American Society for Testing and Materials for austenitic stainless steel seamless pipes used in high-temperature central stations. It emphasizes the long-term performance of steel pipes in high-temperature operating environments and specifies requirements for chemical composition, mechanical properties, dimensional tolerances, heat treatment processes, and testing methods. TP347H is a grade under this standard. With a high carbon content, it exhibits high creep and endurance strength at high temperatures. It is primarily suitable for designs in high-temperature and high-pressure environments, such as power plant boilers, superheaters, and reheaters.
