Alloy C-22 · UNS N06022
A Hastelloy C22 welded pipe is pipe formed from plate or strip and welded along its length, made from Hastelloy C22 to ASTM B619. Welded (ERW / EFW) pipe is economical in larger diameters and thinner walls, and accepted by most codes with the right testing.

Hastelloy C22 Welded Pipe: Why C22 for welded pipes
Welded (ERW / EFW) pipe is economical in larger diameters and thinner walls, and accepted by most codes with the right testing. In Hastelloy C22, the choice usually comes down to the medium and temperature — the rows here are the points buyers check for this exact combination.
| Why this grade | Nickel-alloy tubulars handle acids, chlorides and heat. Hastelloy C22 is picked for mixed oxidising and reducing acids, and weld overlays. |
|---|---|
| Typical service | Chemical processing — Equipment seeing both oxidising and reducing conditions. |
| Welding to carbon steel | A nickel-base filler such as ERNiCr-3 (or ERNiCrMo-3) is used when joining it to carbon steel |
| Matching filler | ERNiCrMo-10 (AWS A5.14) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
