P355NH steel plates etc. EN10028-3 vessel steel for boilers and pressure vessels

P355NH steel plate meets EN10028-3 standard. P355NH steel belongs to fine grain normalizing steel, which is suitable for boiler and pressure vessel use.

Along with the P355NH steel plate, there are other boiler steels under EN10028-3, including P275NH boiler steel, P275NL1 steel, P275NL2 material, P355N boiler steel, P355NL1 boiler steel, P355NL2 steel, P460NH boiler steel, P460NL1 boiler steel, P460NL2 boiler steel.

According to the temperature environment, the classification of EN10028-3 vessel steel is as follows:
Normal temperature vessel steel grade: P355N steel plate.
Steel grade of high temperature resistant vessel: P355NH steel plate.
Low temperature quality grade: P355NL1 steel, P460NL1 steel plate.
Special low temperature quality grade: P355NL2 steel plate, P460NL2 steel plate.

Tensile properties of EN10028-3 steel:
P355N steel plate, P355NH steel plate, P355NL1 steel plate, P355NL2 steel plate, thickness 8-260mm, tensile strength Rm630-450MPa, yield strength: 355-295MPa, elongation after fracture 21-22%.

From the above information, we can find that EN10028-3 P355NH steel plate and other EN10028-3 steel plates are suitable for boiler and pressure vessel.
Their temperature environment is completely different.

Please choose EN10028-3 P355NH steel plate or other EN10028-3 steel plate according to the work environment.
