P295GH is a European standard steel used for boilers and pressure vessels.
Strength: The yield strength is ≥295 MPa, and the tensile strength ranges from 460 to 580 MPa (with possible variations depending on thickness, such as 410 to 530 MPa for thicknesses of 8 to 100 mm).
Ductility: The elongation is ≥20%.
Impact Toughness: It exhibits good low-temperature impact toughness, with impact energy absorption capabilities that meet the requirements for use in low-temperature environments.
Weldability: It possesses excellent welding properties, allowing for high-quality weld seams during the welding process while maintaining the material's structural and performance stability.
Corrosion Resistance: It has certain corrosion resistance properties, effectively resisting oxidation, corrosion, and erosion in general industrial environments.
High-Temperature Resistance: It can operate safely within a temperature range below 500°C, making it suitable for the manufacture of medium to high-temperature pressure vessels and boilers.
Due to its excellent performance characteristics, P295GH steel plates are widely used in the following fields:
Boilers: Such as various thermal power station boilers and boiler steam drums.
Pressure Vessels: Such as nuclear island steel containment vessels and equipment structural components.
Other Equipment: Heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, liquefied petroleum gas cylinders, high-pressure water pipes for hydropower stations, turbine volutes, etc.
In summary, P295GH steel plates play a significant role in industries such as petroleum, chemicals, power, and nuclear energy due to their high strength, high heat resistance, good plasticity and toughness, and excellent welding properties.
