Mechanical Properties
Thickness (mm) | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
---|---|---|---|
0.5–2.0 | 500–650 | 380–325 | ≥20 |
2.1–5.0 | 490–640 | 315–305 | ≥18 |
- Performance Highlights:
- High tensile strength (up to 650 MPa) supports heavy-load structures26.
- Consistent yield strength ensures dimensional stability under stress8.
- 20% elongation enables complex forming (e.g., roll bending, stamping)5.
Applications
- Construction: Roofing, bridge girders, and seismic-resistant frameworks.
- Transportation: Truck chassis, shipbuilding components.
- Industrial Equipment: Pressure vessels, conveyor systems68.
Competitive Advantages
- Durability: Mo (0.1%) enhances pitting resistance in saline atmospheres4.
- Machinability: Low Nb (0.05%) minimizes tool wear during CNC cutting5.
- Certifications: ISO 9001, RoHS, and third-party SGS/BV test reports17.
Packaging & Compliance
- Export Packaging: 3-layer PE film + desiccant, steel edge guards7.
- Traceability: Batch-specific mill test certificates15.
Logical Connectors:
- Addition: Furthermore, the low Nb content…
- Contrast: While Ni enhances corrosion, Cr optimizes cost.
- Example: For instance, bridge builders prioritize 650 MPa tensile strength.
- Cause-Effect: Reduced sulfur minimizes hydrogen-induced cracking.
