P355NH petrochemical steel plate is a kind of low alloy high-strength steel plate, 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 the corrosion resistance, and H stands for the 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 of the petrochemical equipment need to operate in a low-temperature environment.
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 the weld after welding, to meet the requirements of a variety of complex structure manufacturing.
