Annealing
The annealing process for Duplex 2205 involves heating the material to a temperature of approximately 1020°C to 1100°C, followed by cooling in air. This process helps to relieve internal stresses, improve ductility, and homogenize the microstructure, ensuring optimal performance in various applications.
Forging
Forging of Duplex 2205 is typically performed at temperatures between 1100°C and 1200°C. This hot working process enhances the mechanical properties of the steel by refining the grain structure, improving strength and toughness, and ensuring a uniform distribution of phases.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water or Oil | To increase hardness and strength by transforming austenite to martensite. |
| Tempering | 300 - 600 | Air | To reduce brittleness while maintaining toughness and ductility. |
| Stress Relieving | 300 - 500 | Air | To relieve residual stresses from manufacturing processes. |
The careful control of these processes ensures that Duplex 2205 maintains its excellent corrosion resistance and mechanical properties, making it suitable for demanding applications in various industries.
