What it is used for
Flanges, fittings and plate where the drawing says P250GH or C22.8.
Limits
P265GH is the usual switch up. It is not S355.
Delivery
We source P250GH 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
P250GH 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.
