P355NH petrochemical steel plate is a high-quality steel plate material, which is mainly used for manufacturing petrochemical equipment, such as storage tanks, pipelines, reactors and so on. This steel plate has excellent corrosion resistance, strength and low temperature performance, and can maintain a long and stable service life in harsh environments.
P355NH petrochemical steel plate is a kind of low alloy Gold high-strength steel plate, the P in its grade stands for the use of pressure vessels, 355 indicates that the yield strength of the steel is 355MPa, N stands for corrosion resistance, and H stands for welding performance. The steel plate has the following characteristics:
1. high strength: P355NH petrochemical steel plate has high yield strength and tensile strength, which can withstand large pressure and tensile force to ensure the stability and safety of the equipment.
2. corrosion resistance: by adding a certain amount of chromium, nickel and other elements in the steel, P355NH petrochemical steel plate has good corrosion resistance, able to withstand a variety of acids, alkalis, salts and other chemical substances, to extend the service life of the equipment.
3. low-temperature performance: P355NH petrochemical steel plate in the low-temperature environment can still maintain good toughness and ductility, is not easy to brittle fracture, suitable for some need to operate in the low-temperature environment of petrochemical equipment.
4. Welding performance: P355NH petrochemical steel plate has good welding performance, easy to process and weld into a variety of shapes of equipment, and high quality of weld after welding, to meet the requirements of a variety of complex structures manufacturing.
