ASTM A36 Structural Wide Flange H Beams
ASTM A36 Structural Wide Flange H-Beam is a low carbon structural steel grade that meets the American ASTM A36/A36M standard. It has excellent balanced strength, weldability and cost-effectiveness and is widely used in wide flange (W series) H-Beam.
Chemical Composition
| Element | Content Range |
|---|---|
| Carbon (C) | ≤0.25% |
| Manganese (Mn) | 0.80–1.20% |
| Silicon (Si) | ≤0.40% |
| Phosphorus (P) | ≤0.04% |
| Sulfur (S) | ≤0.05% |
| Copper (Cu) | ≤0.20% (optional for enhanced corrosion resistance) |
Common Dimensions (W-Series Examples)
| Model | Depth (mm) | Flange Width (mm) | Web Thickness (mm) | Flange Thickness (mm) |
|---|---|---|---|---|
| W8×31 | 200 | 200 | 9.1 | 14.2 |
| W10×49 | 250 | 250 | 11.0 | 17.3 |
| W12×65 | 300 | 300 | 13.1 | 20.6 |
Comparison with Similar Grades
| Grade | Yield Strength | Key Difference |
|---|---|---|
| S235J0 | ≥235 MPa | Lower strength, EU standard focus |
| A572-50 | ≥345 MPa | Higher strength for heavy-duty use |
Applications of A36 Structural H-Beam
Construction: beams, columns and frames in buildings and bridges.
Industrial Machinery: conveyor systems, crane rails and vehicle chassis.
Shipbuilding: structural components that require corrosion resistance.
Infrastructure: railway tracks and support frames.
Main Advantages of A36H-Beam
High strength-to-cost ratio: suitable for load-bearing structures in buildings and infrastructure.
Weldability: compatible with arc welding, gas shielded welding and other methods without preheating.
Versatility: suitable for galvanizing or painting to enhance corrosion resistance.
