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.

Plates are supplied from stock from our warehousing facilities in Stoke-on-Trent (U.K.), Antwerp (Belgium), and Dubai (U.A.E.).

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

Typical Application of BS 1501 360A /B Steel Plate:
  • Boilers
  • Calorifiers
  • Columns
  • Dished Ends
  • Filters
  • Flanges
  • Heat exchangers
  • Pipelines

DIN standard HI pressure vessel steel has now been superseded with the Euro Norm specification EN 10028. DIN 17155 HII is the German standard for pressure vessel steel. This standard is no longer active and has been superseded by EN 10028, the new Euro Norm standard. Our customers often search and make sales enquiries for this steel grade and as a consequence we have provided grade specification details on this website.

DIN HI steel is a European specified steel for use in pressure vessels, boilers and heat exchangers.The composition of DIN HI steel makes it ideal for applications where elevated working temperatures are the norm and the material is used by fabricators throughout the oil, gas and petrochemical industry.DIN HI steel is a normalized carbon alloy steel and is available ex-stock from our warehouse with mill certification and stamping.

This specification covers carbon steel plates of low- and intermediate-tensile strengths which may be made by killed, semi-killed, capped, or rimmed steel. These plates are intended for fusion-welded pressure vessels. Plates are normally supplied in the as-rolled condition. The steel shall conform to the required chemical compositions. The plates, as represented by the tension test specimens, shall conform to the mechanical property requirements.

A285 steel plates are intended for fusion-welded pressure vessels. Plates are normally supplied in the as-rolled condition.Under ASME SA 285/SA 285M,Carbon steel plate SA285 Grade A,SA285 Grade B and SA285 Grade C is equal to steel grade A285 Grade C,A285 Grade B and A285 Grade A pressure vessel steel sheet.These pressure vessel steel plates A285 Gr A,A285 GrB,A285 GrC owned low and intermediate tensile strengths which may be made by killed,semi-killed,capped or rimmed steel practices according to the end users’ option.

The main differnence for these three carbon steel grades of SA285 Grade A,SA285 Grade B and SA285 Grade C is their yield strength and tensile strength. For pressure vessel steel plate SA285 Grade A,minimum yield strength shall be 165 Mpa and 24Ksi,and SA285 Grade B pressure vessel steel plate owned the minimum yield strength at 185 Mpa and 27 Ksi,then pressure vessel steel plate SA285 Grade C owned the highest yield among them,it shall be above 205 Mpa and 30 Ksi.So steel plate SA285 Grade C is the most common used in the industry.

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.

ASME SA537 Class 1 carbon steel plates are produced for use in pressurised service and are commonly used in the fabrication of industrial pressurised vessels and boilers.

Class 1 plates are provided in normalised condition and are heat treated – as a result, the material displays greater yield and tensile strength than the more standard ASTM A516 grades. Triton supplies ASME SA537 Class 1 plates to the world’s leading fabricators serving the Oil, Gas and Petrochemical industry.
We supply ASME SA537 Class 1 plates from stock or directly from the mill and all of our plates come with their own stamping and mill certification as standard.

ASME SA537 Class 2 steel – a pressure vessel grade steel which is an alloy of carbon, manganese and silicon. The steel is used extensively in the fabrication and manufacture of pressurised tanks, boilers and heat exchangers.

Heat treated using the quenched and tempered method, the material has higher residual tensile and yield strength when compared to pressure vessel grades produced under the ASME SA516 standard. ASME SA537 Class 2 is used extensively by the oil, gas and petrochemical industry.

Triton supplies ASME SA537 Class 2 plates from stock or directly from the mill. As with all our steels, the material comes with its own stamping and mill certification.

DIN 17MN4 has now been superseded by the euro norm specification EN10028. DIN 17155  17 Mn 4 Steel plate for Boiler Pressure Vessel 17 Mn 4  steel plate, DIN 17155  17 Mn 4 steel plates is a kind of material for boiler and pressure vessel steel. DIN 17155  17 Mn 4 steel plates is characterised by a minimum yield strength of 220 – 295 MPa and by good weldability,so 17 Mn 4 steel is mainly used to  for manufacturing boilers, pressure vessels and pipes transporting hot liquids.

We have included details of 17MN4 on this website for cross reference purposes but should you wish to purchase pressure vessel steel to this specification, please consider the following alternatives…
