Alloy C-276 · UNS N10276
A Hastelloy C276 lateral is a fitting with a 45° branch, made from Hastelloy C276 to ASTM B366 WPHC276. Laterals bring in a branch at 45°, reducing turbulence and pressure drop compared to a tee. Common in drainage, slurry and process lines.

Hastelloy C276 Lateral: Why C276 for laterals
Laterals bring in a branch at 45°, reducing turbulence and pressure drop compared to a tee. Common in drainage, slurry and process lines. 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 fittings match nickel-alloy pipe in aggressive media. 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 |

FOB / CIF · Nhava Sheva (JNPT), MumbaiHastelloy C276 Lateral — questions buyers ask
When is a lateral better than a tee?
Where lower turbulence matters — slurries, solids and gravity drainage.
Can Hastelloy C276 laterals 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 laterals?
The material is ASTM B366 WPHC276; dimensions follow MSS SP-43 / manufacturer standard. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Hastelloy C276 lateral?
The alloy price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
Can you supply Hastelloy C276 laterals to NACE MR0175?
Yes. Hastelloy C276 is listed in NACE MR0175 / ISO 15156-3 within its limits; state NACE compliance on the order and it is confirmed on the certificate.
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.
