P275 steel to EN10028-3 is a weldable fine grain steel for pressure vessels. It is intended for moderate to high pressure use and is extensively used by process equipment manufacturers and fabricators in the oil and gas industry.

We have one of the largest stocks of P275 available in Europe with an emphasis on heavy plates. This enables fabricators who have fast track delivery programmes to rely on us due to our high availability and fast delivery on an ex-stock basis.

Typical uses of P275 are for pressure vessels, boilers and heat exchangers. it is also used in gas compression modules for the offshore industry and on FPSOs.

P275 Steel Available in Stock

We stock two P275 grades:

Both grades are available in thicknesses of 5 – 100mm. Standard plates sizes are 2m, 2.5m and 3.5m by 12m but there are other plate dimensions available. Both are mainly stocked from German or Northern European mills and come with EN 10204 certification to either 3.1 or 3.2 (rarely to the EN10204:1990 3.1B)

For customers in Europe P275NH and P275NL2 plate can be ordered direct from Dillinger or from stock from AncoferWaldram. The EN 10028-2 standard can be purchased from the BSI
