Product Introduction Technical Data

Product Introduction

EN10028 P275N steel plate/sheet, under EN standard, we can regard P275N steel plate/sheet for boilers and Pressure Vessels steels.EN10028 P275N steel plate/sheet is for boilers and Pressure Vessels steels, it is a normalized steel plate and sheet which is mainly used for building pressure vessels and boilers and pipes for hot liquid.

Under the standard EN10028_3,steel plate P275N shall be under Normalized delivery condition when processing.These steel grade P275NH and P275N mainly used in pressure vessels and boilers differ from other carbon_manganese structural steel plates owning to its high resistance to pressure at all temperatures when usage.
