EN 10028-3 P275N pressure vessel steels, as a steel specially used for pressure vessel manufacturing, occupies an important position in many engineering applications due to its excellent characteristics.

EN 10028-3 P275N pressure vessel steels is a high-quality non-alloy fine-grained steel. From the perspective of characteristics, it has a good balance of strength and toughness. When subjected to internal pressure, it can effectively resist deformation with its own strength to ensure the structural integrity of the pressure vessel; at the same time, its toughness makes it less likely to brittle fracture when facing impact or temperature changes, ensuring the safe operation of the equipment under complex working conditions.

Main Application Fields

Due to its excellent comprehensive performance, P275N steel plate is widely used in:

Boiler manufacturing: Pressure components of industrial boilers and power plant boilers
Pressure vessels: Reactors and storage tanks in the chemical, petroleum, and natural gas industries
Pipeline systems: Pressure-bearing pipelines for transporting high-temperature liquids (e.g., hot water, hot oil)
Heat exchangers: Industrial heat exchange equipment, such as the high-efficiency shell-and-tube and plate heat exchangers produced by GNEE Group
Low-temperature equipment: Pressure vessels that can operate at appropriate temperatures (-20℃)
