EN 10028-3 Grade P275NL1 normalized or normalized formed (+N)


EN 10028-3 P275NL1 is a low temperature pressure vessel steel plate that meets European standards. It belongs to Grade 1 materials under the EN 10028-3 standard and is designed for manufacturing low temperature pressure vessels used for storing liquids and gases.

P275NL1 steel has good weldability and workability, and exhibits excellent toughness and crack resistance at low temperatures. This material is suitable for various low temperature applications, such as liquefied natural gas (LNG) tanks, liquefied petroleum gas (LPG) tanks, and other low temperature pressure vessels.

According to the EN 10028-3 standard, P275NL1 has strict requirements for chemical composition and mechanical properties. The chemical composition includes limits on elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), niobium (Nb), molybdenum (Mo), and chromium (Cr). In terms of mechanical properties, P275NL1 needs to meet a range of requirements for strength and toughness, such as yield strength, tensile strength, elongation, and impact toughness.

EN 10028-3 P275NL1 is a steel specifically designed for low temperature pressure vessels, with good welding performance and low temperature toughness. It complies with European standards and is widely used in various low temperature storage equipment for liquids and gases.


EN 10028-3 Grade P275NL1 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 P275NL1 can be supplied either in a normalized condition or in a normalized formed (+N) condition, depending on the specific requirements of the application.
