Applications of ASTM A182 F24 Flanges

ASTM A182 Grade F24 vanadium-modified 2.25Cr-1Mo alloy steel flanges are engineered for high-stress, high-temperature industrial piping:

Supercritical Power Plants: Connects superheaters and steam headers using a182 f24 weld neck flange units for high creep strength.
Petrochemical & Hydroprocessing: Secures high-temperature hydrocrackers, reactors, and heat exchangers.
Boiler & Steam Headers: Handles severe thermal cycling lines matching uns k30736 and 7CrMoV10 10 flange standards.
Industrial Process Lines: Directs and terminates high-pressure flows via f24 slip on flange** and F24 blind flange** options (Class 150–2500).

Frequently Asked Questions

What is ASTM A182 F24 flange material?

It is a forged 2.25 chromium, 1 molybdenum steel with vanadium, titanium and boron additions, made to ASTM A182 for high temperature boiler service.

What is the UNS number of A182 F24?

The forging carries UNS K30736. The matching A213 T24 tube and A335 P24 pipe use the same number under their own standards.

What is the equivalent of A182 F24?

The nearest European designation is 7CrMoVTiB10 10, Werkstoff 1.7378. Check the full chemistry and your project code before treating any grade as an exact match.

What is the difference between F24, T24 and P24?

F24 is the forged flange grade, T24 is seamless tube and P24 is pipe. They share a UNS number, but order flanges as ASTM A182 F24.

What is the difference between F24 and F22?

F24 starts from the same 2.25 chromium, 1 molybdenum base as F22, then adds vanadium, titanium and boron for higher strength.

Does an F24 flange need PWHT?

A welded joint on F24 normally needs preheat, controlled heat input and PWHT as set by your piping code and qualified welding procedure.
