ASTM A516 & ASME SA516 Carbon Steel for Moderate Lower Temperature

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.

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.

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.
