Manufacturing Process & Heat Treatment of Duplex 2205 Round Bar
Annealing
Annealing of Duplex 2205 round bars is performed at a temperature range of 1020Β°C to 1100Β°C, followed by air cooling. This process helps to relieve internal stresses and improve ductility, ensuring better formability for subsequent operations.
Forging
The forging process involves heating the Duplex 2205 alloy to approximately 1100Β°C to 1200Β°C. The material is then shaped through mechanical deformation techniques to achieve the desired dimensions and mechanical properties. This process enhances the strength and toughness of the round bars.
Hardening & Tempering
| Process | Temperature Range (Β°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water or Oil | To increase hardness and strength of the material. |
| Tempering | 600 - 800 | Air | To reduce brittleness and enhance toughness. |
| Stabilization | 800 - 900 | Air | To improve corrosion resistance and stabilize microstructure. |
Through these comprehensive manufacturing and heat treatment processes, Duplex 2205 round bars achieve optimal mechanical properties and corrosion resistance, making them suitable for various industrial applications.
