P355GH sheet properties – P355GH steel properties

p295 quality sheet metal

P355gh steel specifications

When we examine the properties of P355gh quality steel, we see that it has higher strength compared to p235 and p295 quality steels. The thickness of p355 quality steel sheets, which have higher heat resistance, generally starts from 3 mm.

1- Cu ≤% 0.30. A lower Cu content and a maximum tin content can be agreed upon at the order, eg. regarding formability. 2- Cr + Cu + Mo + Ni ≤% 0.70 3- For thicknesses less than 6.0 mm, a minimum Mn content of % 0.20 less than specified is allowed. 4-Al / N ≥ 2 5-All content of melting is to indicate and specify in the certification. 6- If resistance to high pressure hydrogen is important, minimum % 0.80 Cr weight percentage can be agreed upon in the order.

EN 10028 – P355GH

Widely used in the petrochemical industry, P355GH is a pressure vessel steel as specified under the Euro Norm standard (EN10028), which replaces the British Standard and DIN standard equivalents.

This normalized steel is used by manufacturers of welded pressure vessels, industrial boilers and heat exchangers worldwide and 
p355 grade steels It is designed to operate at high temperature.
We always supply P355GH from stock. P355 quality sheets are generally between 3mm and 50mm in our stocks.
As with all our steels, it is sent with a material test certificate.
