Due to its high strength, excellent weldability, and low-temperature toughness, P355N steel plate is widely used in the following fields:
Pressure Vessel Manufacturing:
Used for manufacturing boilers, gas storage tanks, liquefied gas tanks, reactors, and other pressure vessels, particularly in the petroleum, natural gas, and chemical industries.
Suitable for medium to low temperatures and moderate pressure environments.
Energy Industry:
Used for producing pressure vessel components in thermal and nuclear power plants, such as steam generators and heat exchangers.
Applicable to liquefied natural gas (LNG) storage and transportation equipment.
Mechanical Manufacturing:
Used for manufacturing heavy machinery components requiring high strength and toughness, such as pressure parts in construction machinery.
Pipelines and Storage Tanks:
Used for manufacturing high-pressure pipelines, storage tanks, and related fittings, especially in scenarios requiring low-temperature performance.
Other Industrial Applications:
Suitable for structural components that need to withstand specific pressure and temperature conditions, such as pressure vessels in chemical equipment, pharmaceutical equipment, and food processing equipment.
