ASME SA516

The ASME SA516 specification is part of the ASME Boiler & Pressure Vessel Code (BPVC) and is a standard which governs the use of carbon steel in weldable industrial boilers and pressure vessels.

The specification sets standards for pressure vessel and boiler quality steel in moderate and lower temperature service. Steel grades which come under this specification are recognised for certain characteristics which include excellent notch toughness and weldability. The material grades vary in performance and such performance is dictated in part by the steels chemical composition.

As a stockholder and global supplier of high quality pressure vessel carbon steel plate, Masteel UK Limited offer range of ASME SA516 grades which is the steel of choice for fabricators serving industry, especially in the oil, gas and chemical supply markets.

We have three ASME SA516 grades available in stock which are normally of western european origin unless you have more specific supply requirements in which case we can source alternatives for you.

HIC tested pressure vessel steel is commonly found in sour gas applications and is particularly suitable for the fabrication of pressure equipment where wet H2S can be a problem due to the long term presence of hydrogen sulphide. Other post production tests can be performed on ASME SA516 either at the mill or by a third party testing house.

ASME SA516 Grade 60

An ideal steel for use in moderate to lower working temperatures, ASME SA516 Grade 60 is used in the fabrication of weldable industrial boilers and steel pressure vessels.

It is a normalized steel which is known for its excellent notch toughness and weldability and is primarily found in pressurised service throughout the oil, gas and petrochemical industry.

At Masteel UK Limited, we carry a significant volume of ASME SA516 Grade 60 carbon steel plates in stock which we ship to our clients worldwide. These plates come with mill certification and are hard stamped so are fully traceable.

ASME SA516 Grade 65

Suitable for a variety of applications in the Petrochemical, Chemical, Oil & Gas Industries, ASME SA516 Grade 65 is a carbon steel used by worldwide fabricators serving these markets.

The steel grade is used in the fabrication of weldable pressure vessels and boilers due to the materials specific composition and characteristics. Excellent notch toughness coupled with good weldability are consistent typical in this grade.

Masteel UK Limited stock this steel grade which is ordered to international standards with additional stringent restrictions applied to the chemical, mechanical and testing requirements. This ensures that clients who have more complex needs can receive steel from us, ex–stock, to their requirements.

ASME SA516 Grade 70

ASME SA516 Grade 70 – one Masteel’s most popular steel grades, the material is highly sort after for welded fabrication in industrial pressure vessels and boilers.

Used throughout the oil, gas and petrochemical industry the material is a normalized steel with excellent weldability and improved notch toughness i.e. the materials ability to absorb energy when a flaw is present.

We keep this material in stock with added stringent restrictions applied to the chemical, mechanical and testing requirements – this ensures that the material is available to you from our warehouse, regardless of your requirements.
