AISI 316L · UNS S31603
An SS 316 / 316L clad plate is carbon-steel plate bonded to a corrosion-resistant alloy layer, made from SS 316 / 316L to ASTM A240. 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.

SS 316 / 316L Clad Plate: Why 316L 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 SS 316 / 316L, 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 | Stainless plate goes into vessels and heavy sections. SS 316 / 316L is picked for chloride-bearing process fluids, marine air and pharmaceutical service. |

FOB / CIF · Nhava Sheva (JNPT), MumbaiSS 316 / 316L 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 SS 316 / 316L clad plates?
The material is ASTM A240; 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 SS 316 / 316L 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.
