Customized type: Profiling fixtures, multi-degree-of-freedom adjustment modules.
| Aspect |
Cast Iron |
Q355 (Structural Steel) |
| Material Category |
Iron-carbon alloy with high carbon content (2-4%), produced by casting. |
Low-alloy high-strength structural steel (GB/T 1591-2018), produced by rolling/forging. |
| Common Types |
Gray Iron, Ductile Iron. |
Replaces the old grade Q345. |
| Key Composition |
High carbon (2-4%), high silicon (1-3%), low manganese (0.1-1%). |
Low carbon (≤0.24%), low silicon (≤0.55%), manganese (1.0-1.6%), with microalloys (Nb, V, Ti). |
| Mechanical Properties |
- Tensile Strength: 120-400 MPa (low) |
- Tensile Strength: ≥355 MPa (actual: 470-630 MPa) |
| - Brittle, low toughness |
- High toughness, impact resistance |
| - High hardness (HB 150-300) |
- Moderate hardness (HB 130-180) |
| - Poor weldability. |
- Excellent weldability. |
| Manufacturing Process |
Casting (molten metal poured into molds). Ideal for complex shapes. |
Hot/cold rolling, forging. Easy to cut, weld, and machine. |
| Applications |
Engine blocks, machine tool bases, pipes, cookware (e.g., cast iron pans). |
Structural frameworks (buildings, bridges), ships, pressure vessels, machinery. |
| Advantages |
Cost-effective, wear-resistant, good vibration damping. |
High strength-to-weight ratio, ductile, suitable for dynamic loads. |
| Limitations |
Brittle, difficult to machine post-casting. |
Requires corrosion protection in harsh environments. |
