FAQ

Frequently asked questions about P265GH

How do P235GH and P265GH differ?

P265GH has a higher yield strength (265 vs. 235 MPa) for higher loads; the service temperature (~400 °C) is comparable.

Is P265GH weldable?

Yes, P265GH welds well; preheating may be advisable at larger wall thicknesses.

Request P265GH?

Grade, standard, size, pressure rating and quantity are enough – on request with an EN 10204 3.1 / 3.2 mill certificate. Your quote usually the same day.

All data are typical values per the relevant EN standards for first orientation – without warranty. The applicable standard and the mill certificate of the delivery are decisive.
