Hastelloy C276 Seamless Pipe: Why C276 for seamless pipes
Seamless pipe is the choice for high pressure, high temperature and critical service where a weld seam is not wanted. In Hastelloy C276, 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 C276 is picked for the most aggressive mixed acids, wet chlorine and hypochlorite. |
|---|---|
| Typical service | Chemical processing — Reactors, heat exchangers and piping for mixed acids. |
| 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-4 (AWS A5.14) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |

Why choose seamless over welded pipe?
No longitudinal weld means uniform strength and corrosion resistance — preferred for pressure and critical service.
Can Hastelloy C276 seamless pipes be welded to carbon steel?
Yes — a nickel-base filler such as ERNiCr-3 (or ERNiCrMo-3) is used when joining it to carbon steel.
Which standard covers Hastelloy C276 seamless pipes?
The material is ASTM B622; dimensions follow ASME B36.19 · B36.10. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Hastelloy C276 seamless pipe?
The alloy price, the size and dimensions, quantity, and the testing and documents required. Send your list and we quote the same working day.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
