Manufacturing Process & Heat Treatment of Duplex 2507
Annealing
Annealing of Duplex 2507 is performed to relieve internal stresses and improve ductility. The process involves heating the material to a temperature range of 1020-1100°C, followed by controlled cooling. This treatment enhances the microstructure, ensuring a balanced phase distribution for optimal mechanical properties.
Forging
The forging of Duplex 2507 involves heating the material to approximately 1200°C, followed by deformation through mechanical means. This process refines the grain structure, increases strength, and improves the overall toughness of the steel. Post-forging, the material is often subjected to cooling treatments to stabilize the microstructure.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Oil or Water | To increase hardness and strength through phase transformation. |
| Tempering | 300-600 | Air | To reduce brittleness and improve toughness after hardening. |
| Stress Relieving | 300-500 | Air | To relieve residual stresses from manufacturing processes. |
The combination of these heat treatment processes ensures that Duplex 2507 exhibits excellent corrosion resistance, high strength, and improved ductility, making it suitable for various industrial applications.
