Manufacturing Process & Heat Treatment of Duplex 2101 Flanges
Annealing
The annealing process for Duplex 2101 flanges involves heating the material to a temperature of approximately 1020-1100Β°C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance corrosion resistance, ensuring the flanges meet industry standards for performance.
Forging
Forging of Duplex 2101 flanges is conducted at elevated temperatures, typically between 950Β°C and 1150Β°C. This process enhances the mechanical properties of the material by refining the grain structure, resulting in improved strength and durability. The forged flanges are then allowed to cool slowly to room temperature.
Hardening & Tempering
| Process | Temperature Range (Β°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil | To increase hardness and strength of the flanges |
| Tempering | 550-700 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 300-500 | Air | To eliminate residual stresses from the forging process |
The combination of these manufacturing processes and heat treatments ensures that Duplex 2101 flanges exhibit excellent mechanical properties and corrosion resistance, making them suitable for a wide range of industrial applications.
