ASTM A213 TP316L / 1.4404 Stainless Steel Seamless Tube Heat Exchanger Tube
ASME SA213/ASTM A213 TP316L Stainless Steel Tube Seamless Heat Exchanger Tubing
Choose TP316L When:
- Operating below 60°C in chloride environments
- Chemical processing with organic acids or alkalis
- Sanitary applications requiring cleanability
- Moderate chloride concentrations (<1000 ppm)
- Temperature cycling applications
- Mixed chemical environments
- Where magnetic permeability must be low
- Welded construction required

Common Specifications & Comparisons
-
vs. ASTM A269 TP316L: A269 covers welded and seamless tubes for general service. A213 is specifically for pressure and high-temperature applications (boiler, superheater, heat exchanger). A213 typically has more stringent testing requirements (e.g., hydrostatic or non-destructive electric tests on every tube).
-
vs. ASTM A312 TP316L: A312 covers seamless and welded pipes for general corrosive service. The main difference is dimensional—A312 is for pipe (NPS sizes), while A213 is for tube (OD/tubing sizes).
-
vs. TP316 / TP316H: The key difference is carbon content. TP316 (0.08% C max) is more prone to sensitization. TP316H (0.04-0.10% C) is for high-temperature strength where intergranular corrosion is not the primary concern.
