EN 10028-3 is the Standard Specification for flat steel products intended for use in pressurised service.The specification EN 10028:3 covers a range of weldable fine grain steels supplied in the normalised condition and intended for pressure purposes. It has three steel grades (P275, P355, and P460) which indicate each grade's minimum yield strength (in MPa) for plates 16 mm thick and below.
