P275N P275NH Boiler Steel Plate
Pressure Vessel Quality Steel Product Description
P275N boiler quality plate and P275NH pressure vessel plate material are European standard special steel plates for boilers and pressure vessels. The implementation standards of P275N boiler steel and P275NH pressure vessel steel plate are EN10028 special technical conditions.
The chemical composition of P275N vessel plate and P275NH pressure vessel plate contains higher carbon elements, giving them higher strength and NMness. At the same time, it is also rich in alloying elements, such as manganese, silicon, phosphorus, etc. These elements can refine the grains during the solidification process of steel and improve the strength and toughness of the steel. In addition, an appropriate amount of nitrogen is added to P275N boiler plate and P275NH boiler plate steel to enhance their NMness and corrosion resistance.
P275N pressure vessel steel and P275NH boiler steel plate not only have high strength, but also possess certain comprehensive high-quality properties such as toughness, fatigue resistance, impact resistance, corrosion resistance, welding and easy processing. It is often used in the pot and pressure vessel manufacturing industry, such as boiler equipment, pressure vessels, reactors, reactors, spherical tanks, pressure pipelines, petrochemical equipment, chemical equipment, petroleum equipment, etc.
