P355GH for Pressure Vessel Steel

EN10028-2 P355GH refers to a specific grade of pressure vessel steel, as defined by the EN 10028-2 standard. It's a normalized steel, meaning it's been heat-treated to ensure a specific microstructure for enhanced strength and weldability. P355GH is particularly suited for applications involving elevated temperatures, making it ideal for pressure vessels, boilers, and heat exchangers in industries like petrochemicals.
