The P355N material is an ordinary room temperature grade steel with good welding properties and some strength.
The following are the main application fields of P355N:
Petrochemical industry: P355N steel plate is used to manufacture pressure vessels such as storage tanks, reactors, separators and heat exchangers.
Electric power industry: In the construction of power stations, P355N steel plate is used to manufacture boiler ladle, hydroelectric power station equipment, etc.
Boiler industry: P355N steel plate is used as the key material for boiler equipment, which is subject to high temperature and high pressure environment.
Petroleum and petrochemical equipment: P355N steel plate is used in the manufacture of petroleum and petrochemical equipment, such as oil and gas tanks, liquefied gas tanks and so on.
Pipeline equipment: P355N steel plate is also used in the manufacture of pipeline equipment, especially in the need to withstand high pressure.
Low Temperature Pressure Vessels: P355N steel plate has important applications in pressure vessels and boiler equipment under low-temperature working environment due to its good cold-impact toughness and weather resistance.
The P355NH material is a high-temperature grade of steel with better high-temperature properties than P355N.
The following are the main application fields of P355NH:
Petrochemical industry: P355NH steel plate can be used to make storage tanks, pipelines, reactors and other equipment, which can improve the corrosion resistance and service life of the equipment.
Marine engineering field: P355NH steel plate can be used to make offshore platforms, ships and other related equipment to improve the weather resistance and impact resistance of the equipment.
Power station industry: P355NH is used in the power station industry to make reactors, heat exchangers, separators and other equipment.
Boiler industry: P355NH steel plate is used to make boiler ladle, high-pressure water pipe and other parts, which ensures the stable operation and safety of the equipment.
Building structure: P355NH steel plate can be used to make bridges, buildings and other structures with high endurance requirements.
The P355NL1 material is a cryogenic grade of steel, suitable for low temperatures above -40°C.
The following are the main application fields of P355NL1:
Oil and gas industry: used in the manufacture of storage tanks, pipelines, refining equipment and other key equipment, which need to withstand high pressure, high temperature and corrosive media erosion.
Buildings and bridges: P355NL1 steel plate is used to manufacture structural parts of high-rise buildings and large bridges, as these structural parts need to withstand huge weight and external forces such as wind.
Cryogenic engineering: In the field of cryogenic engineering, such as liquefied natural gas (LNG) storage and transportation equipment, P355NL1 steel plate can ensure the stable operation of the equipment in the extremely cold environment due to its low temperature toughness.
Shipbuilding: P355NL1 steel plate is used in shipbuilding to withstand the corrosion and wave impacts of the marine environment.
P355NL2 is a special low-temperature grade of steel for low temperatures above -50°C and has higher impact toughness requirements than P355NL1.
The following are the main application fields of P355NL2:
Petrochemical industry: used to manufacture pressure vessels such as storage tanks, reactors, separators and heat exchangers.
Electric power industry: in the construction of power stations, used in the manufacture of boiler ladle, hydroelectric power plant equipment.
Boiler industry: as a key material for boiler equipment, it withstands high temperature and high pressure environment.
Low temperature engineering: It is suitable for pressure vessels as well as boiler equipment under low temperature working environment, with good cold impact toughness.
Vessel manufacturing: manufacture of single-layer coil-welded vessels, multi-layer heat-sleeve coil-welded vessels, multi-layer wrapped vessels and other two or three types of vessels and low-temperature pressure vessels.
