P265GH is a weldable non-alloy quality pressure vessel steel. P265GH has a wide application in the manufacture of pressure vessels, boilers and heat exchangers in the oil and gas industry.P265GH is also used in chemical and pharmaceutical process plants. To some extent it and its big brother P355NL1 are the standard boiler plates. As one of the largest stockists of P265GH plate in Europe we focus on two areas. First we have a large number of very thick P265GH plates to assist companies reducing lead times. Secondly we focus on the quality of our P265GH plates and these are characterised by having a very low level of non-metallic inclusions compared to many other P265GH plates on offer. Our best P265GH plates are also available as HIC resistant steel plates when certified to ASTM A516 Grade 60 with Dicrest 5.

P265GH is the normal equivalent of A516 grade 60 and with many plates there is the possibility of dual certification to both ASME/ASTM standards and EN10028-2

P265GH Specification

EN10028-2 covers alloy and no-alloy steels for pressure vessels with elevated temperature properties. P265GH is useful at moderate temperatures for pressure purposes. At the standard thickness it has a minimum yield strength of 265 MPa. It is normalised by heating through the thickness of the plate to a temperature between 890 to 950°C without holding

It has some heat resistance but for higher temperatures and applications where corrosion is more of a factor then chrome moly steels are recommended. P265GH is specified in EN 10028-2:2009 which replaces the old BS 1501 and DIN17155 standards. It is a steel for use as boiler plate with  a minimum yield strength of 265 MPa. P265 is normally delivered in the normalized condition

P265GH and Pressure Equipment Directive PED 97/23/EC

If the P265GH plate has a mill certificate to EN10204 it complies with the requirement of PED 97/23/EC annex 1 as Annex ZA of EN10028-2 explicitly states that “compliance with the clauses of this standard given in Table ZA.1 confers, within the limits of the scope of this standard, a presumption of conformity with the corresponding Essential Requirements of that Directive and associated EFTA regulations”. And that makes life nice and simple 🙂

P265GH Processing

We can process P265GH plates to your requirements with both flame and laser cutting. With our stock of thick plates we are experienced in preheating and profiling very heavy plates and have 150m of cutting tables enabling us to do large jobs as well as small. P265GH plates can be cut into smaller plates to meet shopping or production requirements or into particular shapes (profiles) to meet you exact engineering requirements.

P265GH Equivalents

There are a fair number of equivalents to P265GH with the most common being the ASTM/ASME A516 Gr 60 plates which it is often dual certified too. Generally the ASTM grade is more popular in the US and Asia with P265GH being more popular in Europe.

P265GH Delivery

We deliver P265GH plates to locations across SE Asia. These include Malaysia, Singapore, Thailand, Indonesia and Vietnam where P265GH plates are not commonly keot in stock and need to be imported. Our strength here is in being able to supply a wide range of heavy plates – above the 50mm that is normally the maximum thickness that is stocked – and a good selection of wide plates – up to 3 metres wide. Wide P265GH steel plates enable customers to save significantly on welding as fewer welds are required.

For customers in Europe P265GH plate can be ordered direct from Dillinger or from stock from AncoferWaldram. The EN 10028-2 standard can be purchased from the BSI
