A Monel 400 clad plate is carbon-steel plate bonded to a corrosion-resistant alloy layer, made from Monel 400 to ASTM B127. 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.

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 Monel 400 clad plates?
The material is ASTM B127; 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 Monel 400 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 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
