Mechanical Properties of Q235 H-Beam
| Property | Value | Description |
|---|---|---|
| Yield Strength (σ₀₆) | 235 MPa | Minimum stress to cause permanent deformation |
| Tensile Strength (σ₁₂) | 375 – 500 MPa | Material resistance to breaking |
| Elongation (A) | 20 – 25% | Indicates good ductility |
| Modulus of Elasticity (E) | 210 GPa | Typical for carbon steels |
| Hardness (HB) | 120 – 180 | Brinell hardness, relatively soft compared to higher grades like Q345 |
Applications of Q235 H Beams
Construction: H beams are essential for frame structures in buildings and bridges. They are often useful for columns, beams, and trusses due to their ability to bear heavy loads.
Industrial Facilities: Used in manufacturing and heavy machinery buildings for strong, durable support structures.
Transportation Infrastructure: For large bridge beams or railway supports that require both strength and flexibility.
Towers and High-rise Buildings: H beams are commonly used for tower supports and other high-load-bearing applications in tall buildings.
