Manufacturing Process & Heat Treatment of Duplex 2205 Round Bar
Annealing
Annealing of Duplex 2205 involves heating the material to a temperature range of 1020-1100°C, followed by a controlled cooling process. This treatment helps to relieve internal stresses, enhance ductility, and improve the overall mechanical properties of the steel.
Forging
The forging process for Duplex 2205 round bars is conducted at temperatures between 1100-1200°C. This method enhances the grain structure, increases strength, and improves toughness. The forged bars are then cooled to room temperature in air or water to maintain their mechanical properties.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Water or Oil | To increase hardness and strength |
| Tempering | 300-600 | Air | To reduce brittleness and improve toughness |
| Stabilization | 850-900 | Air | To enhance corrosion resistance and stabilize the microstructure |
The combination of these processes ensures that Duplex 2205 round bars achieve optimal mechanical properties and corrosion resistance, making them suitable for a wide range of industrial applications.
