UNS S32750 · W.Nr 1.4410
A Super Duplex 2507 clad plate is carbon-steel plate bonded to a corrosion-resistant alloy layer, made from Super Duplex 2507 to ASTM A240. Clad plate puts a thin alloy layer where the fluid is, on a cheaper carbon-steel base that carries the pressure — often far cheaper than solid alloy for thick vessels.

Super Duplex 2507 Clad Plate: Why 2507 for clad plates
Clad plate puts a thin alloy layer where the fluid is, on a cheaper carbon-steel base that carries the pressure — often far cheaper than solid alloy for thick vessels. 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 plate allows thinner vessel walls. 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. |
| Matching filler | ER2594 (AWS A5.9) |

Super Duplex 2507 Clad Plate — questions buyers ask
When is clad plate cheaper than solid alloy?
Usually when the total thickness is well above the corrosion allowance — the thicker the vessel, the bigger the saving.
Which standard covers Super Duplex 2507 clad plates?
The material is ASTM A240; dimensions follow ASTM A264 / A265 · ASME SA-264 / SA-265. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Super Duplex 2507 clad plate?
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 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.
