ASTM A516 Gr 70 · Boiler-quality (BQ) plate
An SA-516 Gr 70 clad plate is carbon-steel plate bonded to a corrosion-resistant alloy layer, made from SA-516 Gr 70 to ASTM A516 Gr 70 · ASME SA-516. 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 SA-516 Gr 70 clad plates?
The material is ASTM A516 Gr 70 · ASME SA-516; 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 SA-516 Gr 70 clad plate?
The steel 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.
