Chemical Composition of P265GH Steel Plate
The controlled chemical composition of P265GH steel plate ensures good weldability, stable strength, and resistance to thermal stress.
| Element | C | Si | Mn | P | S | Cu | N | Cr |
|---|---|---|---|---|---|---|---|---|
| Max / Range (%) | ≤0.20 | ≤0.40 | 0.80–1.40 | ≤0.025 | ≤0.015 | ≤0.30 | ≤0.012 | ≤0.30 |
Low carbon content minimizes the risk of hardening and cracking during welding, even in thick plates.
Mechanical Properties of P265GH Steel Plate
The mechanical properties of P265GH steel plate make it suitable for pressure equipment operating under stress and elevated temperatures.
| Thickness (mm) | Yield Strength ≥ (MPa) | Tensile Strength (MPa) | Elongation ≥ (%) |
|---|---|---|---|
| ≤ 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 | - |
| > 150 | 185 | 390–530 | - |
These properties ensure safe load-bearing performance across a wide thickness range.
Weldability and Heat Resistance of P265GH Steel Plate
Excellent Weldability of P265GH Steel Plate
Thanks to its low carbon and controlled alloy content, P265GH steel plate offers excellent weldability:
- No preheating required for most applications
- Low risk of hydrogen-induced cracking
- Suitable for complex welded pressure vessels
- This makes P265GH an ideal material for large fabricated structures.
-
Heat Resistance for Elevated Temperature Service
P265GH performs reliably at temperatures up to approximately 450°C, maintaining strength and toughness under long-term thermal exposure.
This heat resistance makes it suitable for boiler plates, heat exchangers, and pressure components in continuous operation.
Applications of P265GH Steel Plate in Industry
Due to its balanced strength, ductility, and thermal stability, P265GH is widely used in:
- Boilers and boiler components
- Pressure vessels and reactors
- Heat exchangers and separators
- Storage tanks for oil, gas, and chemicals
- High-temperature piping systems
- Power plants and chemical processing equipment
Its fabrication-friendly nature reduces manufacturing time and cost.
P265GH Steel Plate vs ASTM A516 Grade 60
P265GH is often compared with ASTM A516 Grade 60 for pressure vessel applications.
Key similarities include:
