| Property | Typical Value | Buyer Benefit |
|---|---|---|
| Tensile Strength | 485–620 MPa | Withstands refinery & boiler pressures |
| Yield Strength | Min 260 MPa | Safe load-bearing capacity |
| Elongation | 17–21% | Prevents brittle cracking during forming |
| Impact Resistance | Up to -20°C | Reliable performance in low temps |
| Hardness (BHN) | ≤ 250 | Ensures weldability & machinability |
Designed to handle high pressure, sour environments, and welding stress.
| Element | % Range | Why Controlled? |
|---|---|---|
| Carbon (C) | ≤ 0.21 | Ensures weldability & toughness |
| Manganese (Mn) | 0.55–1.20 | Balances strength & ductility |
| Phosphorus (P) | ≤ 0.010 | Ultra-low to prevent HIC initiation |
| Sulfur (S) | ≤ 0.005 | Controlled for sour gas resistance |
| Silicon (Si) | 0.13–0.45 | Improves structural integrity |
Ultra-low P & S levels = true HIC resistance → trusted by refineries worldwide.
