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.

SA-516 Gr 70 Clad Plate: Why 516-70 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 SA-516 Gr 70, 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 | Carbon and low-alloy plate is the workhorse of pressure vessels and structures. SA-516 Gr 70 is picked for boilers, pressure vessels and storage tanks. |
|---|---|
| Typical service | Pressure vessels — Shells and heads. |
| Matching filler | E7018 / ER70S-6 |

SA-516 Gr 70 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 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 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.
