P355NL1 steel application

P355NL1 steel plate is alloy special steel, steel for pressure equipment, with good plasticity, toughness, cold bending performance and welding performance. It is used to manufacture spherical storage tanks of more than 50 cubic meters, and can also be used to manufacture single-layer coil-welded containers, multilayer heat-sleeve coil-welded containers, multilayer wrap-up containers, etc. Class II and Class III vessels and low-temperature pressure vessels. Widely used in petroleum, chemical, power station, boiler and other industries, used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, and water turbines Volutes and other equipment and components.
