UNS S32750 · W.Nr 1.4410
A Super Duplex 2507 cross is a four-way fitting with branches at 90°, made from Super Duplex 2507 to ASTM A815 WPS32750 (buttweld) · ASTM A182 F53 (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.

Super Duplex 2507 Cross: Why 2507 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 Super Duplex 2507, 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 | Duplex fittings match duplex pipe in chloride service and strength. Super Duplex 2507 is picked for seawater and high-chloride service where strength also matters. |
|---|---|
| Typical service | Offshore & subsea — Seawater injection, firewater and subsea piping. |
| Welding to carbon steel | ER2209 or ER309L(Mo) is used when joining it to carbon steel, under a qualified WPS |
| Matching filler | ER2594 (AWS A5.9) |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |

FOB / CIF · Nhava Sheva (JNPT), MumbaiSuper Duplex 2507 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 Super Duplex 2507 crosss be welded to carbon steel?
Yes — ER2209 or ER309L(Mo) is used when joining it to carbon steel, under a qualified WPS.
Which standard covers Super Duplex 2507 crosss?
The material is ASTM A815 WPS32750 (buttweld) · ASTM A182 F53 (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 Super Duplex 2507 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 Super Duplex 2507 crosss to NACE MR0175?
Yes. Super Duplex 2507 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.
