EN 10028-3 P355NL2 Boiler And Pressure Vessel Steel Plate

EN10028-3 P355NL2 Boiler And Pressure Vessel Steel Plate is a fine-grained normalized weldable steel plate. According to European standards and specifications, it is specially designed for pressure vessels and boilers operating at low temperatures.

Performance Characteristics

1. Excellent low-temperature toughness: It can maintain high impact energy even at -50℃ or lower temperatures, with strong resistance to brittle fracture. This ensures safe use under low-temperature conditions, making it suitable for extreme low-temperature environments such as polar regions or deep seas.

2. Good welding performance: The carbon equivalent is strictly controlled, and preheating before welding may not be required (depending on the thickness). Various welding methods such as manual arc welding, submerged arc welding, and gas shielded welding can be adopted, and the performance of the welded joint is good.

3. Good processing performance: The normalized structure is uniform, and it has good cold forming and cutting performance. It can adapt to different shape requirements and can be subjected to processing operations such as cutting, bending, and curling.

4. Corrosion resistance: Alloying elements such as Cr, Ni, and Mo are added to improve its corrosion resistance, enabling it to resist the erosion of chemical substances such as acids, alkalis, and salts to a certain extent.

1. Low-temperature pressure vessels: Such as LPG/LNG storage tanks, liquid ammonia/liquid oxygen equipment, etc. Its excellent low-temperature toughness can ensure the safety of the vessels during low-temperature storage and transportation.

2. Energy and chemical equipment: Such as low-temperature reactors, separation towers, pipeline systems, etc., which can withstand high pressure and low-temperature environments during chemical reactions.

3. Power station boiler equipment: Such as boiler drums, nuclear reactor pressure shells, high-pressure water pipes of hydropower stations, turbine volutes, etc., which provide guarantees for the safe operation of power stations.

4. Other low-temperature engineering structural parts: Such as ship liquid tanks, etc., which can meet the requirements of structural strength and corrosion resistance of ships when sailing in low-temperature sea areas.
