EN 10028-3 P275NL1 Boiler And Pressure Vessel Steel Plate

EN10028-3 P275NL1 Boiler And Pressure Vessel Steel Plate is a steel plate specified by the European Standard (EN) for pressure vessels, characterized by excellent low-temperature toughness. It is primarily used in the manufacturing of pressure-bearing equipment such as boilers, storage tanks, and reactors.

Key Features

1. High Strength: Maintains stable structural performance under high-stress conditions, making it suitable for heavy-load and high-pressure equipment and structures.

2. Excellent Toughness: Offers good elongation and impact toughness, ensuring structural integrity and stability under impact or vibration, thereby reducing the risk of fractures and damage.

3. Superior Weldability: Can be easily welded with other steel materials to form strong connections, facilitating assembly and processing during manufacturing.

4. Good Corrosion Resistance: Exhibits excellent resistance to various corrosive media such as acids, alkalis, and salts, making it suitable for corrosive environments in chemical, petroleum, and natural gas industries.

5. Hydrogen-Induced Cracking Resistance: Maintains structural integrity and stability in hydrogen-containing environments, making it ideal for equipment and pipelines operating under such conditions.

1. Low-Temperature Equipment: Such as liquefied petroleum gas (LPG) storage tanks, cryogenic separators, and deep-cooling equipment, designed to withstand temperatures as low as -40°C.

2. High-Pressure Vessels: Suitable for reactors and heat exchangers with working pressures ≥10 MPa, as its balanced yield strength and tensile strength (390–510 MPa) ensure optimal load-bearing capacity and plastic deformation resistance.

3. Harsh Chemical Environments: In petroleum and chemical industries where exposure to acidic media (e.g., sulfur-containing oil and gas) is common, its low sulfur and phosphorus content (S ≤ 0.008%) minimizes the risk of corrosion cracking.
