Grade 70 is generally the most common.

What is Stainless Steel CLADDED PLATES

For large structures, stainless steel fabrication is not an economically viable option since the material is too costly for large fabrications. Stainless steel A simple solution to this problem is the cladding technique. It involves using carbon steel for manufacturing the equipment or appliances and then covering them in a thin layer of stainless steel (3mm).  

By cladding, we mean joining two dissimilar metals together using pressing, extrusion, and rolling techniques that bind two dissimilar metals together under high pressure and pressure temperature.

In addition to being extremely durable, stainless steel cladding has high resistance to the elements.

With the stainless steel cladding, the chromium content (min 20%) reacts with oxygen to form a passive layer of chromium oxide (Cr2O3) that is non-porous and restricts further corrosion of the steel. I can also use stainless steel cladding with carbon steel and low alloy steel. 

Plastic deformation of metals causes bonding due to intense collisions. The stainless steel cladding process causes a bond between two metals. Hot rolling can strengthen the bond between carbon steel and stainless steel. 

It is used in various applications such as chemical processes, oil refining, offshore oil production, etc. It is also used in power generation units with high temperatures and stress corrosion between the steel layers.

Difference Between SA516 Grade 70 Plate and SA516 Grade 60 Plate

We are not discussing grades today but rather explaining why we are discussing grades. Use the SA516 Gr.60 Steel Plate for your upcoming project or business venture. In that case, you should be aware of its higher tensile strength compared to the SA516 Gr.70 Steel Plate and that it can support a greater amount of weight before breaking.

Steel sheets A516 GR.70 are made of iron, chrome, nickel, and molybdenum alloys with 70,000 psi yield strength. Steel plate A516 GR.60, made of iron, chrome, nickel, and manganese, has a yield strength of 60,000 psi and is used in various construction sectors, particularly the automobile industry. Aside from its high tensile strength, corrosion resistance, and weldability (it can withstand temperatures up to 2200°F), it is also used in construction.

Because of its high chromium concentration and low carbon content, A516 GR.70 steel plate is excellent for use in engines and other high-pressure or severe applications due to its high chromium concentration.

Since A516 GR.60 has a higher carbon content and lower chromium content than A516 GR.70, it offers less corrosion resistance than A516 GR.70 but still offers good resistance to oxidation at atmospheric pressure (approximately 14 psi).

Uses of SA 516 GR 70 + STAINLESS STEEL

It is estimated that pressure vessel manufacturers and fabricators use a significant amount of ASTM A516 Grade 70 boiler quality plates in the oil and gas industry for making process equipment. This material is also used on production platforms for skid-mounted pressure vessels and modules, and a significant amount of it is used downstream in refineries and industrial plants.

Reliability of ASTM A516 Grade 70 Plates

A large pressure vessel requires high levels of reliability. Can reduce the production risk if you choose plates made by mills with a strong reputation for quality that the end user is familiar with. It is easier to deal with the situation if you import pressure vessel plates overseas and then find a defect.

As a result of our experience, German steel mills offer ASTM A516 Gr 70 plates with fewer defects – especially as they become thicker. German steel is an insurance policy for some companies, but it prevents problems from happening at all.

There are also several other benefits besides improved reliability compared to steels of another origin. Retesting plates with better physical and chemical characteristics is often easier, which means the chance of them failing a test is lower. Also, plates are often tougher and more weldable.

Availability of ASTM A516 Grade 70 Plates

Whenever our customers require ASTM A516 Grade 70 plates on an ex-stock basis, they only want to shop for plates in one location. We have one of the largest stocks of ASTM A516 Grade 60 steel plates in Northern Europe, so we can most meet all your needs from stock.

Even if you require 20 or 30 plates, we can handle the possibilities for you even if you require a large amount of A516 grade 70 plates. When steel plates are unavailable locally, there is a trade-off between increased welding and wider plates when fabricating boilers and pressure vessels. As plates widen, delivery becomes slower because they can’t go on container vessels. To match your production schedule to the optimum choice of A516 70 plate, we have options at 2m, 2.5m, and 3m, so you can choose per your requirements.

Pressure Vessel Plate or Boiler Plate?

There is no right or wrong in classifying boiler and pressure vessel plates. Some other steel plate companies classify all steel plates as pressure vessel plates: there is no right or wrong.

A key feature of Prosaic Steel for potential customers is that we stock, process, and distribute all of the most popular Boiler and Pressure Vessel specifications like ASTM A516, ASME SA516, eN 10028-3, and BS 1501. Let us match our stocks to your requirements while you call the steel whatever you like.


HIC occurs when carbon steel is corroded by hydrogen sulfide, which is the cause of HIC (Hydrogen Induced Cracking). The problem of wet hydrogen sulfide (H2S) cracking in steel has been a problem since the 1950s in petroleum refining and upstream oil and gas processing. The problem is increasingly important for equipment manufactured from potentially sensitive carbon-manganese (C-Mn) steels as more fields rich in H2S are exploited. Often, sour service conditions are described as working conditions in which wet H2S is present and sour gas is also used to describe these conditions.

Aside from inhibiting the formation of hydrogen gas at the surface, H2S also promotes its absorption into the steel to reduce the possibility of it escaping. In water that contains hydrogen sulfide, steel will rust and produce hydrogen as it is exposed to water containing hydrogen sulfide. As a result, hydrogen atoms can become trapped and eventually crack at temperatures below 200 degrees Celsius, leading to embrittlement and cracking.

Using steel pressure vessels in industries such as oil and gas processing requires robust steel resilience to the long-term corrosive effects of hydrogen sulfide in sour service applications. To provide better H2S resistance, the properties of C-Mn steels have been progressively developed to improve chemistry, cleanliness, homogeneity, and microstructure.
