Hastelloy C22 / Alloy C22 Flanges – ASTM B564 UNS N06022
Forged Alloy C22 flange solutions for demanding mixed, oxidizing and reducing chemical environments after project-specific corrosion review.
Jawaban rekayasa cepat
Hastelloy C22 and Alloy C22 refer to UNS N06022, a nickel-chromium-molybdenum alloy with tungsten. ASTM B564 is the forged-product specification used for applicable C22 flanges; UNS N06022 is the correct UNS designation.

Pemilihan bahan
Alloy C22 offers broad corrosion resistance in many severe chemical-process environments, but no alloy is universally immune. Suhu, konsentrasi, kontaminan, celah-celah, fabrication and actual process conditions must be reviewed using relevant corrosion data.
Matching-material note: C22 and C276 are different alloys and should not be interchanged by name. Match adjoining products to their correct product-form standard and obtain written engineering approval for any proposed substitution.
Kontrol kualitas tersedia
- PMI and controlled material segregation
- Heat number and EN 10204 3.1 ketertelusuran
- Corrosion testing, UT or PT when ordered
- Dimensi, facing and marking inspection
Aplikasi yang umum
Aplikasi adalah isyarat seleksi, bukan persetujuan menyeluruh. Media proses, tekanan, suhu, data korosi, kelelahan, fabrication and code requirements govern final suitability.

Pertanyaan yang sering diajukan
What is the correct UNS number for Hastelloy C22?
The correct designation is UNS N06022. Purchase documents should also state ASTM B564 untuk flensa palsu.
Are Alloy C22 and Hastelloy C22 the same?
Alloy C22 is the generic grade name and Hastelloy C22 is a recognized trade name associated with UNS N06022. The UNS number and product standard provide the clearest procurement identity.
Can C22 replace C276?
Not without engineering review. They have different chemistry and may behave differently in the actual service environment, fabrication route and project design.
