P355NL1 steel and P355NL1 steel plate possess excellent strength, toughness, and weldability, making them suitable for a variety of industrial applications. Their main uses are as follows:
Low-Temperature Pressure Vessels: P355NL1 steel plate is specifically designed for low-temperature environments and is used to manufacture equipment such as liquefied natural gas (LNG) storage tanks and low-temperature reactors. It maintains good impact toughness at temperatures as low as -40°C or even -50°C, preventing brittle fracture.
Offshore Engineering Structures: In offshore engineering, P355NL1 steel plate is used to fabricate structural components such as columns for deep-sea drilling platforms and hulls for Floating Production, Storage, and Offloading (FPSO) vessels. It exhibits resistance to seawater corrosion and fatigue, with a fatigue limit of ≥250 MPa, enabling it to withstand the harsh conditions of the marine environment.
Nuclear and Thermal Power Equipment: This steel plate is used to manufacture critical equipment such as nuclear reactor containment vessels and supercritical boiler drums. It possesses high-temperature creep strength and radiation stability, ensuring the long-term safe operation of equipment under high-temperature and radiation conditions.
Specialized Transportation Equipment: P355NL1 steel plate is suitable for manufacturing specialized transportation equipment such as low-temperature liquid nitrogen tankers and chemical transport tanks. It features a lightweight design (with a density of 7.85 g/cm³) and high safety, meeting the stringent requirements for the transportation of hazardous materials.
Construction and Bridge Structures: In the construction field, P355NL1 steel plate is used for the structural frames of high-rise buildings and the roof truss structures of large stadiums. In bridge engineering, it is applicable to components such as bridge decks and main girders of small- to medium-span bridges, capable of withstanding complex loading conditions.
Machinery Manufacturing: P355NL1 steel plate is used to fabricate frames and support structures for large-scale equipment such as mining machinery and construction machinery, including crushers, screeners, cranes, and excavators, ensuring the stable operation of equipment under harsh conditions.
Energy and Petrochemical Equipment: In the energy industry, P355NL1 steel plate is used to manufacture equipment such as boiler pressure vessels, heat exchangers, and gas storage tanks. In the petrochemical sector, it is used for ethylene cracking units, low-temperature separation towers, and pipeline systems, capable of withstanding high-pressure and low-temperature conditions.
Transportation Equipment: It is suitable for the manufacture of transportation equipment such as railway tankers and ship pressure cabins, maintaining structural integrity and safety under low-temperature or high-pressure environments.
