EN10028-3 P275NL2 Pressure Vessel Steel Plate

EN10028-3 P275NL2 is a pressure vessel steel grade that is widely used in the fabrication of pressure vessels and boilers due to its excellent mechanical properties and resistance to low-temperature environments. This grade is compliant with the European standard EN10028-3, which specifies requirements for flat products for pressure equipment made of weldable fine-grain steels.
Chemical Composition:
The chemical composition of P275NL2 is carefully controlled to ensure the necessary mechanical properties and weldability. The typical chemical composition includes:

• Carbon (C): ≤ 0.16%
• Silicon (Si): ≤ 0.50%
• Manganese (Mn): ≤ 1.50%
• Phosphorus (P): ≤ 0.025%
• Sulfur (S): ≤ 0.015%
• Nickel (Ni): ≤ 0.30%
• Chromium (Cr): ≤ 0.30%
• Molybdenum (Mo): ≤ 0.08%
• Copper (Cu): ≤ 0.30%
• Niobium (Nb): ≤ 0.05%
• Titanium (Ti): ≤ 0.03%
• Vanadium (V): ≤ 0.05%

Mechanical Properties:
The mechanical properties of P275NL2 are characterized by its high strength and toughness, which are crucial for pressure vessel applications. Typical mechanical properties are as follows:

• Yield Strength: ≥ 275 MPa
• Tensile Strength: 430 - 580 MPa
• Elongation: ≥ 22%
• Impact Energy (at -40°C): ≥ 40 Joules (longitudinal test specimen)

Heat Treatment:
P275NL2 is generally supplied in a normalized condition. Normalization is a heat treatment process that involves heating the steel to a temperature above its upper critical point and then cooling it in air. This process refines the grain structure and improves the mechanical properties of the steel.
Low-Temperature Impact Test:
The steel grade is subjected to a low-temperature impact test to ensure its suitability for use in low-temperature environments. The impact energy values are measured at -40°C, which is a critical temperature for many applications where the equipment may be exposed to cold conditions.
Available Dimensions:
TJC Steel Group offers P275NL2 pressure vessel steel plates in a wide range of sizes to meet various project requirements. The typical available dimensions include:

• Thickness: 6mm - 300mm
• Width: 1500mm - 4020mm
• Length: 3000mm - 18000mm

Main Applications:
P275NL2 is commonly used in the construction of pressure vessels, boilers, heat exchangers, and other similar equipment. Its excellent mechanical properties and resistance to low temperatures make it suitable for applications in the petrochemical, chemical, oil and gas, and power generation industries.
TJC Steel Group Supply Cases:
TJC Steel Group has a proven track record of supplying high-quality P275NL2 steel plates to various industries worldwide. One notable supply case involved the delivery of P275NL2 plates for a major oil refinery project in the Middle East. The plates were used to construct high-pressure vessels that required exceptional toughness and strength at low temperatures. TJC's ability to provide the material in large quantities and within a tight schedule was crucial to the project's success.
In another instance, TJC supplied P275NL2 steel plates for a chemical processing plant in Europe. The plates were used to fabricate pressure vessels that needed to withstand aggressive chemical environments at elevated temperatures. TJC's material met the stringent quality requirements and was delivered on time, contributing to the plant's smooth operation.
In conclusion, EN10028-3 P275NL2 is a reliable choice for pressure vessel applications requiring high strength and toughness, especially in low-temperature conditions. TJC Steel Group's extensive experience in supplying this grade of steel plate ensures that clients receive material that meets the highest standards of quality and performance.
