P355NH pressure vessel plate
P355NH PVQ Steel Plate Products Description
P355NH pressure vessel plate is a high-performance steel plate that complies with European standard EN 10028-3 and is designed for pressure vessels. In P355NH pressure vessel steel plate, "P" stands for pressure vessel steel, "355" stands for the minimum yield strength of 355 MPa, and "NH" stands for a specific quality grade suitable for high temperature environments.
P355NH boiler steel plate can maintain good toughness at low temperatures and has strong impact resistance. The alloy elements such as chromium and nickel contained in P355NH steel boiler plate can improve corrosion resistance.
Application areas of P355NH boiler plate: P355NH pressure vessel steel is widely used in the fields of petroleum, chemical industry, power stations, boilers, etc., such as the manufacture of storage tanks, pipelines, reactors, heat exchangers, separators and other equipment, as well as boiler heating surfaces and pressure vessels. P355NH vessel plate can improve the corrosion resistance and service life of equipment.
