Manufacturing Process & Heat Treatment of Duplex 2101
Annealing
The annealing process for Duplex 2101 involves heating the steel to a temperature range of 950-1050°C, followed by controlled cooling. This process helps to relieve stresses, improve ductility, and refine the microstructure, ensuring optimal mechanical properties for further processing.
Forging
Forging of Duplex 2101 is carried out at elevated temperatures, typically between 1100-1200°C. This hot working process enhances the mechanical properties by aligning the grain structure and increasing strength. The forged bars are then allowed to cool slowly to avoid cracking and maintain integrity.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil | Increase hardness and strength |
| Tempering | 400-600 | Air | Reduce brittleness and enhance toughness |
| Stabilization | 600-800 | Air | Improve corrosion resistance and stabilize microstructure |
The combination of these processes ensures that Duplex 2101 round bars achieve the desired mechanical properties and corrosion resistance, making them suitable for various industrial applications.
