P275NL2 Boiler and Pressure Vessel steel Description

P275NL2 pressure vessel steel plate is a European standard steel plate, which is a non-alloy quality steel, and the corresponding number is 1.1104. P275NL2 has high strength and good weldability and can be used to manufacture various pressure vessels, such as storage tanks, gas tanks and boilers. P275NL2 low alloy steel is also widely used in the chemical, shipbuilding and petroleum industries.

The chemical composition of P275NL2 low alloy pressure vessel steel mainly includes carbon, silicon, manganese, phosphorus, sulfur and other elements. Among them, the content of carbon element is low, which can improve the weldability and processability of steel. The high content of silicon can improve the heat resistance and corrosion resistance of steel. The content of elements such as manganese, phosphorus, and sulfur also has an important impact on the performance of steel. This alloy steel is often used to make automotive parts, locks and other mechanical equipment. P275NL2 pressure vessel steel can withstand working conditions in high-temperature and high-pressure environments, and can also resist hydrogen electrical corrosion and the formation of stress corrosion cracks.

EN10028-3 P275NL2 pressure vessel steel is a low-alloy steel with excellent properties. In order to ensure the performance of the steel, strict quality control is required to ensure the correctness of chemical composition, heat treatment and processing. P275NL2 container steel complies with the EN10028 standard. The grades under the same standard include: P275NL1, P355NH, P355NL1, P355NL2, P420NH, P420NL1, P420NL2, P460NH, P460NL1, P460NL2, etc.
