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 1020-1080°C, followed by a controlled cooling process. This treatment aims to relieve internal stresses, enhance ductility, and improve the overall mechanical properties of the steel.
Forging
Forging of Duplex 2101 flanges is performed at temperatures between 1100-1300°C. The forging process enhances the material's strength and toughness by refining the grain structure. This results in improved performance characteristics and dimensional accuracy in the final product.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil | To increase hardness and strength of the flanges. |
| Tempering | 600-700 | Air | To reduce brittleness and improve toughness. |
| Stress Relieving | 500-600 | Air | To eliminate residual stresses from the manufacturing process. |
The combination of these manufacturing and heat treatment processes ensures that Duplex 2101 flanges possess the required mechanical properties and corrosion resistance, making them suitable for various industrial applications.
