Alloy 625 · UNS N06625
An Inconel 625 clad plate is carbon-steel plate bonded to a corrosion-resistant alloy layer, made from Inconel 625 to ASTM B443. 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.

Inconel 625 Clad Plate: Why 625 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 Inconel 625, 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 plate goes into vessels and tube sheets in aggressive media. Inconel 625 is picked for seawater, high strength and high temperature in one alloy. |
|---|---|
| Typical service | Offshore & subsea — Risers, flowlines and clad pipe. |
| Matching filler | ERNiCrMo-3 (AWS A5.14) |

Inconel 625 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 Inconel 625 clad plates?
The material is ASTM B443; 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 Inconel 625 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.
