P280GH / 1.0426 pressure vessel steel
P280GH is non-alloy pressure vessel steel for flanges to EN 10222-2. W.Nr. 1.0426. Close to P265GH / 1.0425 — it is the flange certificate, not the tube certificate.

What it is used for
Welding neck flanges type 11 and other EN 1092-1 flanges where P280GH is specified.
Limits
P265GH when it is plate or tube. P250GH when 250 is sufficient.
Delivery
We source P280GH from European mill partners as plate, flat bar, round bar, cut to your dimensions and ship the certificate with the material. Typical condition: +N / +NT. From a single cut piece to larger lots — with no minimum charge, so you do not have to buy a full commercial length to get what you need.
Certificates and documentation
P280GH can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. On pressure-bearing material the certificate is part of the product: standard, condition and tests must be on the enquiry, and 3.2 must be agreed before the material is locked at the mill. EN 10204 3.1 can be supplied on a wide range of our materials — 3.2 and third party by project, when the mill can issue it.
