P265GH Steel Plate Specification under EN 10028 Standard
P265GH belongs to non-alloy quality steel for pressure purposes under the EN 10028 standard. Its equivalent Chinese grade is 25MnG.
Key specification highlights include:
Standard: EN 10028
Steel type: Pressure vessel steel plate
Delivery condition: Normalized (N)
Deoxidation: Fine grain killed steel
Application temperature: Elevated temperature service
Compared with ordinary carbon steel, P265GH offers better toughness, formability, and long-term service reliability.
Chemical Composition of P265GH Steel Plate
The controlled chemical composition ensures excellent weldability and stable mechanical performance.
| Element | C | Si | Mn | Cr | Ni | Mo | Nb | V | P | S | Al | Cu |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Content (%) | ≤0.20 | ≤0.40 | 0.80–1.40 | ≤0.30 | ≤0.30 | ≤0.08 | ≤0.02 | ≤0.010 | ≤0.025 | ≤0.010 | ≥0.020 | ≤0.012 |
This balanced composition helps P265GH steel plate maintain good strength while avoiding brittle fracture during service.
Mechanical Properties of P265GH Steel Plate by Thickness
The mechanical performance of P265GH steel plate varies with thickness, ensuring safety across different design requirements.
| Thickness (mm) | Tensile Strength Rm (N/mm²) | Yield Strength ReL (N/mm²) |
|---|---|---|
| ≤16 | 410–530 | 265 |
| 16 < t ≤ 40 | 410–530 | 255 |
| 40 < t ≤ 60 | 410–530 | 245 |
| 60 < t ≤ 100 | 410–530 | 215 |
| 100 < t ≤ 150 | 400–530 | 200 |
| 150 < t ≤ 250 | 390–530 | 185 |
These values make P265GH suitable for both thin-wall and thick-wall pressure equipment.

Application
What is P265GH steel equivalent to?
P265GH is a European material standard steel grade commonly used in pressure vessel and boiler applications. Its approximate equivalent in ASTM standards is ASTM A516 Grade 60.
What is the tensile strength of P265GH?
Steel for boiler making and pressure vessels with a minimum yield strength of 265 MPa and a tensile strength of 410 to 530 MPa.
What is the difference between P265GH and S355?
P265gh is a pressure vessel grade steel having superior chemical concentration than the S355 grade. The S355 grade is a structural steel module, having superior mechanical properties compared to the P265gh grade.
What is the difference between P235GH and P265GH?
P235GH: Has a minimum yield strength of 235 MPa, making it suitable for moderate-pressure applications. Its tensile strength ranges between 360-500 MPa. P265GH: Offers a higher yield strength of 265 MPa and a tensile strength of 410-570 MPa, providing better performance in higher-pressure environments.
What is the temperature range of P265GH material?
The unalloyed steel is designed for use in continuous operation up to approx. 400 °C and for pipes up to approx. 450 °C wall temperature. Sheets made of P265GH are characterized by good weldability and the steels can be easily cold and hot formed.
