Mechanical Properties
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Impact Energy (J) |
| S235JR | 235 | 360-510 | 26 | 27 (at 20°C) |
| S235J0 | 235 | 360-510 | 26 | 27 (at 0°C) |
| S235J2G3 | 235 | 360-510 | 26 | 40 (at -20°C) |
| S235J2G4 | 235 | 360-510 | 26 | 40 (at -20°C) |
| S355J0 | 355 | 470-630 | 22 | 27 (at 20°C) |
Steel Grade
- S235JR: General structural steel with a minimum yield strength of 235 MPa.
- S235J0: Similar to S235JR but with improved impact properties at 0°C.
- S235J2G3: Offers better impact resistance at -20°C.
- S235J2G4: Similar to S235J2G3 but with slightly different chemical composition.
- S355J0: Higher yield strength of 355 MPa, suitable for more demanding applications.
Application
These structural steel tubes are widely used in:
- Construction of buildings and bridges
- Manufacturing of machinery and equipment
- Automotive industry
- Structural components in various engineering applications
Possible Alternative Grades
- S235: Lower strength but good for less demanding applications.
- S275: Offers a balance between strength and ductility.
- S355: Higher strength, suitable for heavy-duty applications.
