| 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. |

Operation and Maintenance Guide
1 Installation Requirements
The basic flatness should be ≤ 0.1mm/m. It is recommended to install it on a steel structure bracket or a concrete base.
Use a level to adjust and ensure that the global horizontal error is ≤ 0.05mm/m.
2 Daily Operation Specifications
Use special positioning pins when installing the fixture. Directly striking the tabletop is prohibited.
Welding spatter should be cleaned up in a timely manner to avoid blocking the positioning holes.
3 Maintenance
Daily: Clean the hole system with compressed air.
Weekly: Check the flatness of the tabletop.
Monthly: Apply antirust oil (non-nitrided version).
