Alloy C-22 · UNS N06022
A Hastelloy C22 clad plate is carbon-steel plate bonded to a corrosion-resistant alloy layer, made from Hastelloy C22 to ASTM B575. 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.

Hastelloy C22 Clad Plate: Why C22 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 Hastelloy C22, 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. Hastelloy C22 is picked for mixed oxidising and reducing acids, and weld overlays. |

Hastelloy C22 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 Hastelloy C22 clad plates?
The material is ASTM B575; 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 Hastelloy C22 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.
