EN 10028

EN 10028 Part 2 & 3 is the euro norm specification for flat steel products intended for use in pressurised service. The specification covers non–alloy and alloys steels as well as weldable fine grain steels.

EN 10028 sets standards for steel used in weldable industrial boilers and pressure vessels. The specification has the same status of the old DIN and BS Standards which EN 10028 has now superseded.

Terminology

When reviewing EN 10028 pressure vessel steel grades in subsequent pages of our website please note that…

  • GH – is ideal for use in elevated working temperatures
  • NH – for moderate to high temperature service
  • NL1 – is ideal for use in low temperatures
  • NL2 – is ideal for use in especially low temperatures

As a steel stockholder, Masteel UK Limited offer EN 10028 specified boiler and pressure vessel quality steel from stock which is in most cases of Western European Origin – this is known for its superior quality. Our carbon steel plates come with mill certification and are stamped to provide full traceability.

Alternatively, the customer can arrange testing via a third party testing house.

Our pressure vessel steels often end up in fabricated steel tanks used in sour service environments which are commonly found in the oil and gas industry. We can test your pressure vessel and boiler steel for its susceptibility to hydrogen induced cracking (see HIC steel), which is often a requirement for the supply of carbon steel plates into such industries

EN 10028 – P235GH

EN 10028 – P235GH

P235GH is a European specified steel for use in pressure vessels, boilers and heat exchangers.

The composition of this 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.

P235GH is a normalized carbon alloy steel and is available ex-stock from our warehouse with mill certification and stamping. This EN10028 steel grade supersedes the older BS and DIN standards (Grades BS 1501-161-360A and DIN H 1, respectively).
