Manufacturing Process & Heat Treatment of Super Duplex Flanges
Annealing
The annealing process for super duplex flanges involves heating the material to a temperature range of 1000°C to 1100°C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the flanges.
Forging
Forging of super duplex flanges is performed at elevated temperatures, typically between 1050°C and 1200°C. This process involves shaping the metal through compressive forces to achieve desired dimensions and improve the material's grain structure, resulting in enhanced strength and toughness.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Minimize residual stresses |
The manufacturing and heat treatment processes of super duplex flanges are critical in ensuring they meet the stringent requirements for performance in demanding environments. Proper execution of these processes results in flanges that exhibit excellent mechanical properties and corrosion resistance, suitable for various industrial applications.
