P265GH (EN standard) and ASTM A516 Gr. 60 (ASME/ASTM standard) are essentially equivalent carbon steels for pressure vessel/boiler use, both offering similar mechanical properties (minimum yield strength ~265 MPa for thinner sections, good weldability), but differ in their governing standards, with P265GH used under European norms (EN 10028-2) and A516 Gr. 60 under American (ASTM/ASME), making them interchangeable for most applications requiring moderate service.
