SA213 TP304L is a low-carbon austenitic stainless steel (18% Cr, 8% Ni, low C) used in U-bend boiler tubes for high-corrosion resistance and flexibility in heat exchangers.

Primary Applications

Heat Exchangers & Condensers - Shell & tube heat exchangers (U-bends allow thermal expansion). Surface condensers in power plants (resists steam/condensate corrosion).
Boilers & Superheaters - Recovery boilers (handles flue gas condensates). Low-pressure steam boilers (where chloride stress corrosion is a concern).
Petrochemical & Refining - Reboilers, feedwater heaters (resists acidic/alkaline conditions). Refinery heat recovery systems (exhaust gas applications).
Food & Pharmaceutical Processing - Sanitary heat exchangers (non-reactive, easy to clean).
Marine & Desalination - Desalination plant tubing (resists saltwater pitting/crevice corrosion).

Why Use SA213 TP304L U-Bend Tubes?

✔ Excellent corrosion resistance (vs. carbon steel in acidic/chloride environments)
✔ Low carbon content (0.03% max) - prevents sensitization & intergranular corrosion
✔ Good weldability - no post-weld heat treatment required
✔ High ductility - U-bends withstand thermal expansion stresses
✔ Oxidation resistance up to ~800°C (1472°F)

Comparison with Other Grades

Grade	Key Features	Best For
TP304L	Low carbon, general corrosion resistance	Most heat exchangers, food/pharma
TP316L	Added Mo (2-3%), better chloride resistance	Marine, desalination, harsh chemicals
TP321	Ti-stabilized, resists sensitization	High-temp exhausts, aircraft
TP347	Nb-stabilized, superior creep resistance	Superheaters, high-pressure steam

Common FAQs

Can TP304L handle high-pressure steam?

Yes, but for >500°C (932°F), TP321/TP347 is preferred due to better creep strength.

Why U-bend instead of straight tubes?

Absorbs thermal expansion (reduces stress on tube sheets). Compact design (saves space in heat exchangers).

How to prevent stress corrosion cracking (SCC)?

Avoid chloride exposure >60°C (140°F). Use TP316L if chlorides are present.

What's the max operating temperature?

Continuous: ~800°C (1472°F) (oxidizing environments). For pressure service: ~425°C (797°F) per ASME limits.

How to inspect U-bend tubes?

Dye penetrant (PT) for surface cracks. Radiography (RT) for internal defects.
