ASME SA213 TP316 (UNS S31600) Stainless Seamless Heat Exchanger Tube
ASME SA213 TP316 (UNS S31600) is a seamless austenitic stainless steel tube specifically designed for high-temperature service in heat exchangers, boilers, and superheaters. It offers excellent corrosion resistance, high-temperature strength, and oxidation resistance due to its molybdenum-enhanced composition. This material complies with the ASME Boiler and Pressure Vessel Code, ensuring reliability in critical thermal applications.

2. Key Adventages
- Superior Corrosion Resistance
Molybdenum-enhanced (2%~3% Mo) resists pitting and crevice corrosion in chloride environments.
High chromium-nickel content resists acids, alkalis, and oxidation in harsh conditions (e.g., chemical, marine).
- High-Temperature & Pressure Performance
Maintains strength at high temperatures with excellent oxidation/creep resistance for boilers & heat exchangers.
The maximum temperature resistance can reach 1040℃ (1900℉).
- Excellent Fabrication & Weldability
Seamless cold/hot forming allows bending/flaring without cracking.
Compatible with TIG/MIG welding, no post-weld heat treatment required.
- Long Service Life & Low Maintenance
Smooth seamless interior minimizes scaling, reducing maintenance costs.
Long-term cost efficiency due to extended service life.
