Product Description

ASME SA213 / ASTM A213 T11 / 13CrMo4-5 Alloy Steel Heat Exchanger Tube

ASTM A213 Grade T11 (EN 13CrMo4-5) is a seamless, ferritic 1.25Cr-0.5Mo alloy steel tube specifically manufactured for high-temperature boiler, superheater, and heat exchanger service. It offers improved creep strength and oxidation resistance over carbon steel up to ~570°C, making it the standard choice for subcritical power plant superheaters, reheaters, feedwater heaters, and HRSG evaporators. The EN equivalent 13CrMo4-5 (1.7335) is widely used in European boilers and pressure vessels.

Heat Treatment (Required by ASTM A213)

All T11 tubes must be furnished in one of the following heat-treated conditions:

Fully annealed – Heat to 855–900°C (1570–1650°F), cool in furnace.
Isothermal annealed – Heat to 845–900°C (1550–1650°F), cool to 705–745°C (1300–1375°F), hold, then air cool.
Normalized and tempered – Normalize at 900–960°C (1650–1760°F), then temper at 620–760°C (1150–1400°F).

Application

1. Superheater Tubes (Boilers & HRSGs)

2. Reheater Tubes

3. Water Wall Tubes (Furnace Walls)

4. Economizer Tubes (High‑Temperature Inlet Section)

5. Feedwater Heater Tubes

6. Heat Exchanger Tubes in Refineries & Petrochemical Plants

7. Waste Heat Recovery Units (WHRU)

8. Nuclear Power Plant (Conventional Island)

9. Biomass / Waste‑to‑Energy Boilers

10. Industrial Boilers (Process Steam)

Tube ends were clean, dimensions consistent. Our crew didn't run into fit-up issues.

It's hot and humid here, and our old wrap-on tubes used to rust like crazy. Switched to your extruded ones—the aluminum fin covers the steel pipe perfectly, so corrosion shouldn't be an issue.

Tube ends were clean, dimensions accurate. Our fitters didn't complain about fit-up.
