P265GH
Data verifiedP265GH is the EN 10028-2 workhorse pressure-vessel steel for European boiler and vessel fabrication — the normalized C-Mn grade that sits a step below P355GH in strength. Its GH suffix marks it as proven for high-temperature (elevated-temperature) service.

Equivalents overlap in chemistry and use but are not always identical — see our equivalents guide before substituting in certified designs.
Applications & Processing
Applications: Boilers, steam generators, pressure vessels, heat exchangers, hot-water and process plant across the EU PED market.
Processing: Excellent weldability by all standard processes; the European default where A516 Gr.70 is the American default — certificates differ, service is equivalent.
FAQ
- P265GH vs A516 Gr.70?
- Near-equivalents for ambient/elevated-temperature vessels: P265GH is the EN grade (265 MPa yield), A516 Gr.70 the ASTM grade (260 MPa yield). Either is normally acceptable where the design code allows both.
