Manufacturing Process & Heat Treatment of Duplex S32205 Flanges
Annealing
Annealing of Duplex S32205 flanges involves heating the material to a temperature range of 1020-1100 °C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance the overall microstructure of the steel, ensuring optimal performance in demanding applications.
Forging
The forging process for Duplex S32205 flanges involves shaping the material at elevated temperatures, typically between 1050-1200 °C. This method enhances the mechanical properties of the steel by refining the grain structure, resulting in improved strength and toughness.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050-1150 | Water or Oil | Increase hardness and strength |
| Tempering | 600-800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300-500 | Air | Minimize residual stresses |
