ASTM A213 TP316L U-tube is an austenitic stainless steel seamless tube designed for high temperature and high pressure environments, and complies with the requirements of the ASME boiler and pressure vessel specifications. The cold-bent U-shaped structure significantly improves the heat exchange efficiency and is widely used in the core heat transfer system of power station boilers, petrochemical refining, and nuclear power equipment.
2. Core Material Properties
Super corrosion resistance
Molybdenum content of 2.5-3.0%, significantly improving the ability to resist pitting/crevice corrosion
Low carbon design (C≤0.03%) avoids the risk of intergranular corrosion and passes the ASTM A262 Practice E test
Chloride tolerance of 2000ppm, far exceeding 304/316 materials
Excellent high temperature performance
Continuous working temperature range: -196°C to 800°C
Elongation of ≥14% at 815°C (ASTM E21 test verification)
Precision manufacturing process
Cold rolling process ensures surface roughness Ra≤0.8μm
Solution treatment (1050-1150℃ water quenching) achieves grain size ≥7
U-shaped bending radius accuracy control ±0.5D, ovality ≤5%
