Alloy C-276 · UNS N10276
A Hastelloy C276 cross is a four-way fitting with branches at 90°, made from Hastelloy C276 to ASTM B366 WPHC276 (buttweld) · ASTM B462 / B564 (forged). Crosses join four pipes in one fitting. They are used less than tees because of stress concentration, but save space in fire-water and utility systems.

Hastelloy C276 Cross: Why C276 for crosss
Crosses join four pipes in one fitting. They are used less than tees because of stress concentration, but save space in fire-water and utility systems. 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 |

Hastelloy C276 Cross — questions buyers ask
Why are crosses less common than tees?
They concentrate stress at four junctions; most designers use two tees unless space is critical.
Can Hastelloy C276 crosss 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 crosss?
The material is ASTM B366 WPHC276 (buttweld) · ASTM B462 / B564 (forged); dimensions follow ASME B16.9 · B16.11. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Hastelloy C276 cross?
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 crosss 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 or 3.2 certificates available on request / as specified in the PO; dimensional reports as required. PMI can be arranged depending on product and requirements, as specified in the PO.
