EN 10028-3 P275N steel plate used for boiler and pressure vessel

EN 10028-3 P275N steel plate introduction
Under EN 10028 standard, EN 10028-3 P275N steel plate shall be in normal delivery state during processing. These steel grades P275Nh-steel-plate-material-for-vessel-steel-plate.html target=_blank class=infotextkey>P275NH and EN 10028-3 P275N steel plate, which are mainly used in pressure vessels and boilers, are different from other carbon manganese structural steel plates because they have high pressure resistance at any temperature when used.
