Chemical Composition of EN 10028-2 P265GH Steel Plate
Strict chemical control ensures weldability and reliable service at elevated temperatures.
Main Chemical Elements (Max %)
| Grade | C | Si | Mn | P | S | Al (min) | N |
|---|---|---|---|---|---|---|---|
| P265GH | 0.20 | 0.40 | 0.80–1.40 | 0.025 | 0.015 | 0.020 | 0.012 |
Additional Alloying Elements
| Cr | Cu | Mo | Nb | Ni | Ti | V |
|---|---|---|---|---|---|---|
| 0.30 | 0.30 | 0.08 | 0.020 | 0.30 | 0.03 | 0.02 |
Carbon Equivalent (Ceq):
Ceq = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15 %
This low carbon equivalent improves weldability and reduces cracking risk.
