EN 10028-3 Grade P355NL2 normalized or normalized formed (+N)

EN 10028-3 Grade P355NL2 is a normalized fine grain steel plate that meets European standards for pressure vessel applications. It belongs to the EN 10028-3 standard and is designed for use in low temperature pressure vessels.


P355NL2 steel exhibits good weldability and high impact resistance, making it suitable for various low temperature applications. This grade of steel offers excellent mechanical properties, including high strength and ductility, which are crucial for pressure vessels operating at low temperatures.

According to the EN 10028-3 standard, P355NL2 has specific requirements for chemical composition and mechanical properties. The chemical composition includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and other alloying elements. These elements are controlled within specified limits to ensure the desired properties of the steel.

In terms of mechanical properties, P355NL2 must meet criteria for yield strength, tensile strength, elongation, and impact energy absorption. These properties determine the material's ability to withstand pressure and perform under low temperature conditions.Particularly cryogenic weldable fine grain steel for application in pressure vessel and steel construction.

EN 10028-3 Grade P355NL2 is a normalized fine grain steel specifically developed for low temperature pressure vessel applications. It provides good weldability, high impact resistance, and reliable mechanical properties, making it suitable for use in various industries where low temperature operations are required.

EN 10028-3 Grade P355NL2 can be supplied in two different conditions: normalized or normalized formed (+N).

Normalized: This condition refers to the steel being subjected to a controlled heating and cooling process to achieve uniform properties throughout the material. It involves heating the steel above its critical temperature, holding it at that temperature for a specific time, and then allowing it to cool in still air. Normalizing improves the mechanical properties of the steel, such as strength and toughness.

Normalized formed (+N): This condition indicates that the steel has undergone a forming process after normalization. The forming process could involve shaping, bending, or any other method of altering the steel's shape. After the forming process, the steel is again subjected to normalization to restore its desired properties.


EN 10028-3 Grade P355NL2 can be supplied either in a normalized condition or in a normalized formed (+N) condition, depending on the specific requirements of the application.
