P355NH boiler and pressure vessel steel plate P355NH high-strength low-alloy steel

P355NH Boiler and Pressure Vessel steel Description

P355NH boiler and pressure vessel steel plate is a high-strength low-alloy steel plate with good mechanical properties and heat resistance. P355NH pressure vessel steel has high post-break elongation and area shrinkage, good plasticity and toughness, and can meet various mechanical processing and Forming requirements. P355NH steel plate has good cold bending performance and welding performance. Its cold bending forming ability is good and can meet the requirements of general cold bending forming; P355NH pressure vessel plate has excellent welding performance and is easy to weld. Mainly used to manufacture equipment such as pressure vessels and boilers.

P355NH pressure vessel steel implements EN10028 European standard, also known as normalized weldable fine-grained steel plate. P355NH steel plate has excellent corrosion resistance through special smelting process and alloy composition design. At normal temperature, its atmospheric corrosion resistance is equivalent to that of 16MnR steel plate, while in high temperature environment, its corrosion resistance is better than that of 16MnR steel plate. In addition, P355NH steel plate also has good alkali corrosion resistance and seawater corrosion resistance. P355NH is used in petroleum, chemical industry, power stations, boilers and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas bottles, Hydropower station high-pressure water pipes, turbine volutes and other equipment and components.

EN10028 P355NH boiler steel plate has excellent properties such as high strength, high toughness, fatigue resistance, impact resistance, corrosion resistance, welding and easy processing. Usually P355NH steel plates are delivered in normalized, thermo-mechanically rolled, quenched and tempered states. P355NH also has other grades under the same standard EN10028: P275NH, P275NL1, P275NL2, P355N, P355NH, P355NL1, P355NL2, P460NH, P460NL1, P460NL2
