Manufacturing Process & Heat Treatment of Duplex 2304
Annealing
The annealing process for Duplex 2304 involves heating the material to a temperature range of 1020-1100°C, followed by air cooling. This treatment helps to relieve internal stresses, improve ductility, and refine the grain structure, enhancing the overall mechanical properties of the steel.
Forging
Forging of Duplex 2304 is typically performed at temperatures between 1050-1200°C. This process involves shaping the metal through compressive forces, which improves its strength and toughness by refining the grain structure. Post-forging, the material is usually cooled in air or water to achieve desired properties.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Water or Oil | Increase hardness and strength |
| Tempering | 600-800 | Air | Reduce brittleness and relieve stresses |
| Stabilization | 800-900 | Air | Improve corrosion resistance and stability |
The combination of these manufacturing processes and heat treatments ensures that Duplex 2304 exhibits exceptional mechanical properties and corrosion resistance, making it suitable for a wide range of applications in various industries.
