HP325 steel plate
With stable mechanical performance, excellent weldability, and strong pressure resistance, HP325 steel plate for pressure vessels has become a preferred material in industries such as oil & gas, petrochemical, and energy engineering.
Chemical Composition of HP325 Steel Plate
The chemical composition of HP325 steel plate material is strictly controlled to ensure both strength and weldability. Low impurity levels help reduce cracking risks during forming and welding.
| Element | Content (%) |
|---|---|
| C | ≤0.20 |
| Si | ≤0.40 |
| Mn | 0.80–1.50 |
| P | ≤0.025 |
| S | ≤0.015 |
Lower phosphorus (P) and sulfur (S) content significantly improves toughness and ensures safer performance in pressure vessel applications.
