What Are ASTM A213 T11 Alloy Steel Seamless Tubes?
These Chrome-Moly T11 tubes are seamless steel pipes designed for boilers and superheaters, meaning they can handle pressure well. The ASME SA213 T11 specification means they have good heat resistance. This makes them a solid choice if you're looking for a "T11 superheater tubes supplier" or need to compare the ASTM A213 T11 price per meter. As a T11 tube stockist, we supply these tubes (also known as UNS K11597 T11) which offer good strength even at high temperatures.

ASTM A213 T11 Tubes Heat Treatment & Size Accuracy (Tolerances)
The ASTM A213 T11 heat treatment process helps these tubes meet their strength targets, and accurate sizes ensure they fit correctly.
Heat Treatment Requirements
ASTM A213 T11 tubes are normalized and tempered:
Normalize: Heating to around 1650°F (900°C) and then air cooling is part of the ASTM A213 T11 heat treatment. This helps make the steel's internal structure better.
Temper: Then, reheating them between 1250°F (675°C) and 1350°F (730°C) – depending on thickness and use – makes them less brittle and tougher. Ask us about T11 tube lead time to help plan your project.
NACE MR0175 & Impact Testing (Optional)
If you need tubes for environments with sour gas (meeting NACE MR0175) or need extra toughness, we can supply T11 tubes that pass impact tests (like Charpy V-notch tests at low temperatures). Just tell us what you need.
Dimensional Tolerances – Ensuring a Precise Fit
- OD < 1″ (25.4 mm): ±0.10 mm
- OD ≥ 1″: ±1%
- Wall Thickness (Cold-Finished): ±10%
- Wall Thickness (Hot-Finished): ±12.5% or per ASTM A1016
Types & Forms of A213 T11 Tubes We Offer
- Seamless Hot‐Finished Tubes: A good value choice for many high-heat uses.
- Seamless Cold‐Finished Tubes: Have a smoother surface, more exact sizes, and often better strength.
- U‐Bend & Bending Services: For heat exchangers, made to your drawings.
- Custom forms like Inconel‐Cladded Duplex Tubes: Can be supplied if requested.

FAQs about ASTM A213 T11 Tubes
What material is A213 T11?
ASTM A213 T11 tubing (ASME SA213 T11 tubing) is made from Chrome Moly Alloy material, used in high temperature applications, specifically in boilers and superheaters. Because of its uses, the A213 T11 tubing is almost always much more expensive than pipe made from standard carbon pipes.
What is T11 steel grade?
A T11 tube is a low ferritic stainless steel of SA 213 grade. The T11 Tube includes a composition of 1-1.50% chromium and 0.44-0.65% of Molybdenum, and 0.30-0.60%of manganese. T11 tube also has minuscule amounts of silicon, carbon, potassium, and sulfur in its composition.
What is the difference between T11 and T22 steel?
The only difference between T11 and T22 alloy steel tubes is their mechanical and chemical properties. The T11 alloy steel tube has a lower molybdenum percentage, providing the T22 alloy steel tube with better mechanical properties and higher creep resistance.
