|---|---|---|---|
| T ≤ 16 | 265 | 410–530 | 22 |
| 16 < T ≤ 40 | 255 | 410–530 | - |
| 40 < T ≤ 60 | 245 | 410–530 | - |
| 60 < T ≤ 100 | 215 | 410–530 | - |
| 100 < T ≤ 150 | 200 | 400–530 | - |
| T > 150 | 185 | 390–530 | - |
These values confirm P265GH is suitable for both thin-wall and thick-wall pressure equipment.
Chemical Composition of P265GH Boiler Steel Plate
Strict chemical control guarantees weldability and long-term service stability.
Main Chemical Elements (Heat Analysis, Max %)

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.
