P355NL1 Boiler and Pressure Vessel steel Description

P355NL1 steel is a low-temperature carbon steel used for pressure vessels. Its main features are good low-temperature toughness and welding performance. P355NL1 steel complies with European standard EN10028-3 and P355NL1 is a type of non-alloy and alloy steel. EN10028-3 is a European standard involving fine-grained steel for pressure vessels, including P275NL1, P275NL2, P355N, P355NH and other grades of steel.

P355NL1 pressure vessels steel plate has excellent impact and fracture resistance at low temperatures and is widely used in the manufacturing of pressure vessels, storage tanks and pipelines under low temperature conditions, such as liquefied gas storage tanks, liquid nitrogen pipelines, etc. It can withstand operating temperatures as low as -50 degrees Celsius and maintain high strength and reliability. The heat treatment process of P355NL1 steel can have a certain impact on its corrosion resistance. P355NL1 steel plate can also be used in shipbuilding, fertilizer plants, pulp and paper industry, sugar industry and other occasions where pressure-resistant equipment needs to be used in low temperature environments.

EN10028-3 P355NL1 boiler and pressure vessels steel plates also have good welding properties and can be connected by conventional welding methods. P355NL1 is widely used in petroleum, chemical industry, power stations, boilers and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, boiler drums, liquefied petroleum gas bottles, high-pressure water pipes in hydropower stations, Turbine volute and other equipment and components.
