EN 10028-3 P460NL2 Boiler And Pressure Vessel Steel Plate

EN10028-3 P460NL2 Boiler And Pressure Vessel Steel Plate is a European standard steel plate for boilers and pressure vessels, particularly suitable for low-temperature environments.

Performance Characteristics

High Strength: Yield strength ≥460 MPa, tensile strength between 570-720 MPa. For plates with thickness ≤16 mm, the maximum tensile strength can be up to 730 MPa; for thicknesses of 40-60 mm, yield strength ≥430 MPa; and for thicknesses of 60-100 mm, yield strength ≥400 MPa.

Excellent Low-Temperature Toughness: Impact energy ≥27 J at -50°C, ensuring outstanding impact resistance in extreme cold environments and preventing brittle fracture of the steel at low temperatures.

Good Weldability: Can be processed using various methods such as flame cutting and laser cutting. It is compatible with common welding techniques, and the welded joints exhibit good strength and toughness, meeting the manufacturing requirements of complex structural components.

Resistance to Hydrogen-Induced Cracking: Demonstrates good resistance to hydrogen-induced cracking when exposed to corrosive H₂S environments. Its crack susceptibility can be assessed through hydrogen-induced cracking tests to ensure reliability in specific conditions.

Typical Applications of EN10028-3 P460NL2 Boiler and Pressure Vessel Steel Plate:

1. Petroleum and Chemical Industries: Used in reactors, heat exchangers, separators, spherical tanks, oil and gas storage tanks, and liquefied gas tanks, capable of withstanding high-temperature, high-pressure, and corrosive environments.

2. Power Plants and Boiler Industry: Employed in manufacturing boiler drums, high-pressure water pipes for hydropower stations, and turbine spiral casings, ensuring safe and stable operation of power plants and boilers.

3. Other Fields: Also used in large-scale steel structures such as bridges and buildings, as well as in oil and gas pipelines, and storage and transportation equipment in the petrochemical and natural gas industries, especially in engineering projects in extremely cold regions.
