PVQ steel plate is used for the production of pressure vessels, which are closed containers designed to hold gases or liquids at a pressure substantially different than the ambient pressure.
Pressure vessel and boiler quality steel are commonly found throughout the oil industry (including inshore and offshore), the petrochemical industry and the gas production industry. The companies in these industries set the highest demands in terms of quality, testing and conditions of supply, and Sunny Steel have all the necessary expertise to meet these demands.
Specification and Grades
ASTM A285
The ASTM A285 specification covers low to intermediate tensile strength carbon steel for use in non–critical pressure vessel applications.
The plate is used as a weldable material in the fabrication of pressure vessels and industrial boilers using fusion welding i.e. the joining of the material by melting them together to form one. The plate is offered at a maximum thickness of 50mm for all grades to ensure internal robustness.
As ASTM A285 does not promote high tensile strength, it is used commonly in the fabrication of storage tanks and low pressure temperature controlled vessels.
ASTM A285 Grade C
Although only effective in lower pressure environments, ASTM 285 Grade C is found throughout industry in a wide range or low pressurised applications. ASTM A285 Grade C is used in a range of other applications including structural, mechanical and general engineering purposes.
ASTM A285 Grade C is a low to intermediate yield steel used in the fabrication of carbon steel pressure vessels and boilers.
The material has good forming and welding characteristics under conventional methods.

ASME SA285
Covering low to intermediate tensile strength carbon steel for use in non–critical pressure vessel applications, ASME SA285 sets standards for plates used by fabricators in the production of weldable pressure vessels & boilers.
As the standard is specifically for low to intermediate tensile strength, the steel plates supplied under this standard should be used in low pressure storage tanks, boilers and vessels.
We supply high quality ASME SA285 Grade C pressure vessel steel plate which is available ex–stock from our UK warehouse and can be shipped worldwide.
ASME SA285 Grade C
ASME SA285 Grade C is a low to intermediate tensile strength pressure vessel grade steel. Used in the fabrication of pressure vessels and boiler tanks, SA285 Grade C should not be considered for use in high pressure applications.
The material has good weldability under conventional methods using fusion welding. Plates supplied to this standard are normally delivered ‘as rolled’ unless otherwise specified.

ASTM A537
The ASTM A537 specification covers heat treated carbon steel plates for pressure vessel applications.
ASTM A537 Class 1 plates are supplied in the normalised condition whilst Class 2 plates are quenched and tempered. ASTM A537 carbon steel plates promote greater tensile and yield strength than pressure vessel plates supplied under the ASTM A516 standard.
Our plates can be shipped from our own stockholding in the UK or directly from the mill itself. As we are part of the mill rolling program we can ship plates to our customers to meet their deadlines on a global basis. The steel can also be tested to your specific requirements.
We also have own own steel processing plant which means that we can supply ASTM A537 steel profiles cut to your specific requirements using our CAD controlled multi–head flame cutters.
ASTM A537 Class 1
ASTM A537 Class 1 carbon steel plates are engineered to be used in pressure vessel applications.
The material is a normalised steel which is heat treated and as a consequence displays greater yield and tensile strength than the more standard ASTM A516 grades.
We can supply ASTM A537 Class 1 plates from stock or directly from the mill. We also offer an in house profiling service where the material can be cut to the size or shape you require.

BS1501 – 161-360A/B
BS-161-360A/B (often referred to as Grade 360A/B) is a British Standard specified steel which is ideal for use in fabricated steel pressure vessels and boilers.
The BS specification has now been superseded by the Euro Norm specification EN 10028, however, many companies in the industry still refer to this standard, so we have included details of the grade for cross reference purposes.
There are two types BS1501-161-360 available which are …
- Type A :
Denotes specified min. room temperature tensile properties - Type B :
As per Type A but with elevated temperature properties

ASTM A353
ASTM A353 specification covers 9% nickel steel plates that are double-normalized and tempered, and this steel is used for cryogenic welded pressure vessels. These steel plates are usually limited to a thickness of 50 mm.
ASTM A353 9% nickel is can operate at temperatures lower than -196oC, which is needed for the containment and transportation of cryogenic gases such as argon, nitrogen, and oxygen.
This steel plate has a tensile strength of 690-825 MPa and yield strength 515 MPa. These properties make ASTM A353 9% nickel a fantastic choice for cryogenic pressure vessel steel production.
