| Product List |
ASME SA213 TP347H is a high-temperature austenitic stainless steel tube designed for heat exchangers, boilers, and superheaters in demanding industrial environments. Its superior resistance to oxidation, corrosion, and creep makes it ideal for applications in power plants, petrochemical refineries, and other high-temperature processes. YUHONG has extensive experience in supplying and manufacturing SA213 TP347H tubes, ensuring high-quality performance and reliability.
High-Temperature Strength: Excellent creep resistance at elevated temperatures (up to 800°C).
Corrosion Resistance: Enhanced resistance to intergranular corrosion and oxidation due to stabilized niobium (Nb) content.
Weldability & Formability: Suitable for welding and forming without post-weld heat treatment.
Long Service Life: Durable performance in harsh environments, reducing maintenance costs.
