S355J2H is a European standard hot-finished seamless or welded structural hollow section specified under EN 10210-2. The "S" stands for structural steel, "355" indicates minimum yield strength of 355 MPa (at 16mm thickness), "J2" denotes impact testing at -20°C, and "H" signifies hollow section.
S355J2H Rectangular Tube is widely used in load-bearing structures, steel frameworks, bridges, cranes, and heavy machinery where high strength, good weldability, and low-temperature toughness are required.
Unlike cold-formed hollow sections (EN 10219), S355J2H under EN 10210 is hot-finished, which results in more uniform mechanical properties, better weldability, and less residual stress.

Per EN 10210-2, S355J2H has the following chemical requirements (ladle analysis).
| Element | Content (%) | Notes |
|---|---|---|
| Carbon (C) | ≤ 0.22 | Controlled for weldability |
| Silicon (Si) | ≤ 0.55 | Deoxidizer |
| Manganese (Mn) | ≤ 1.60 | Provides strength |
| Phosphorus (P) | ≤ 0.030 | Low for toughness |
| Sulfur (S) | ≤ 0.030 | Low for cleanliness |
| Nitrogen (N) | ≤ 0.012 | Controlled |
| Carbon Equivalent (CEV) | ≤ 0.45 | Ensures good weldability |
*CEV = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15*
| Wall Thickness (mm) | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|
| ≤ 16 mm | ≥ 355 | 470 – 630 | ≥ 20 |
| 16 – 40 mm | ≥ 345 | 470 – 630 | ≥ 20 |
| 40 – 63 mm | ≥ 335 | 470 – 630 | ≥ 20 |
| 63 – 80 mm | ≥ 325 | 470 – 630 | ≥ 20 |
| 80 – 100 mm | ≥ 315 | 470 – 630 | ≥ 20 |
Elongation measured on 5.65√So gauge length.
| Temperature | Minimum Impact Energy (KV) |
|---|---|
| -20°C | ≥ 27 J (longitudinal) |
The "J2" designation guarantees 27 Joules minimum at -20°C, making S355J2H suitable for cold climate and dynamic loading applications.
| Grade | Yield (≤16mm) | Impact Temp | Best For |
|---|---|---|---|
| S355J2H | ≥ 355 MPa | -20°C | General structural, cold regions |
| S355J0H | ≥ 355 MPa | 0°C | Mild climate structures |
| S355NH | ≥ 355 MPa | -20°C (EN 10210-3) | Higher toughness requirements |
| S275J2H | ≥ 275 MPa | -20°C | Lower strength, cost-effective |
Primary Use: Structural frameworks and load-bearing construction
