Chemical Composition of EN 10025-2 S355J2
Strict chemical control ensures excellent weldability and structural reliability.
| C (max) | Si (max) | Mn (max) | P (max) | S (max) | Cu (max) | CEV (Typical) |
|---|---|---|---|---|---|---|
| 0.20% | 0.55% | 1.60% | 0.025% | 0.025% | 0.55% | ≤0.45 |
Low Carbon Equivalent (CEV) reduces the risk of welding cracks and minimizes preheating requirements.
Mechanical Properties of S355J2 H Profile Steel
| Property | Value |
|---|---|
| Yield Strength (t≤16mm) | ≥355 MPa |
| Tensile Strength | 470 – 630 MPa |
| Elongation | ≥22% |
| Impact Test | 27J at -20°C |
The -20°C Charpy V-notch test ensures the steel maintains toughness in cold climates.
Why Choose S355J2 Instead of S355JR?
Many buyers confuse S355JR and S355J2, but the difference is critical.
| Grade | Impact Test Temperature | Application |
|---|---|---|
| S355JR | +20°C | Standard structures |
| S355J2 | -20°C | Cold climates, offshore, wind towers |
Because S355J2 is tested at -20°C, it prevents brittle fracture in cold environments and dynamic load conditions.
