ASTM A516 Grade 60 is a boiler and pressure vessel quality steel which is ideal for moderate and lower temperature service. The material is used extensively by industrial boiler and pressure vessel fabricators who provide manufacturing support to the oil, gas and petrochemical industry. The steel has good weldability and excellent notch toughness.

At Triton we keep a healthy stock of ASTM A516 Grade 60 carbon steel plates. These plates come with mill certification in compliance with EN10204 3.1 or EN10204 3.2. and are hard stamped and fully traceable. Alternatively we can ship to you directly from the mill.

Please refer to the data tables below. Should your require a pressure grade steel with greater tensile and yield strength, please refer to ASTM A516 Grade 65 and/or ASTM A516 Grade 70.

ASTM A 516 Gr.55 Plate
A516 steel plate, also known as PVQ516 steel plate, is carbon steel with specifications for pressure vessel plates and moderate or lower temperature service. A516 steel plate is intended primarily for service in welded pressure vessels where improved notch toughness is important. Plates 1.50” and under in thickness are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both. Plates over 1.50” in thickness shall be normalized.

HIC (Hydrogen Induced Cracking) is the result of a corrosive reaction between carbon steel and hydrogen sulphide. Wet hydrogen sulphide (H2S) cracking in steel has been a problem in petroleum refining and upstream oil and gas processing since the 1950s. Working conditions where wet H2S prevails are often described as sour service conditions and the term sour gas can be also be used in this context. As more fields rich in H2S are exploited, and this is increasingly the case, the problem is increasingly significant for equipment fabricated in potentially sensitive carbon-manganese (C-Mn) steels.

Steel in contact with water containing H2S will corrode producing hydrogen at its surface. H2S not only inhibits the formation of hydrogen gas, so reducing the opportunity for it to escape, but promotes its absorption in to the steel. At typical working temperatures below 200 degrees Celsius hydrogen atoms can become trapped causing embrittlement and ultimately cracking.

The use of steel pressure vessels in industries such as oil and gas processing requires a robust steel which is resilient to the long term corrosive effects of hydrogen sulphide in sour service applications. In order to provide better H2S resistance the properties of C-Mn steels have been progressively developed to improve chemistry, cleanliness, homogeneity, and microstructure.

Triton Alloys  provides a complete range of plate tested for its resistance to hydrogen induced cracking (HIC) in wet H2S (sour service) environments. The plate is manufactured by Industeel (part of the Arcelor Mittal Group) & by ISD HUTA, Poland and is guaranteed by them to have the following minimum properties:

• Crack Length Ratio (CLR) less than 5 %
• Crack Thickness Ratio (CTR) less than 1.5%
• Crack Sensitivity Ratio (CSR) less than 0.5%

The plate is tested to NACE TM 0284-03 Solution A and certified to EN 10204 3.2 (Lloyds). It is compatible with many of the world’s most stringent proprietary specifications including Petrobras N1706, Saudi Aramco 01-SAMSS-016, EEMUA 179, Axens IN-43, Shell MESC 74/125, and Shell DEP 31.22.10.32.We are able to offer plates to ASME / ASTM SA / A 516 Grades 60/65/70.
