Manufacturing Process & Heat Treatment of Super Duplex 2507 Flanges
Annealing
Annealing of Super Duplex 2507 flanges is conducted to relieve internal stresses and improve ductility. The typical annealing temperature is around 1020°C to 1100°C, followed by rapid cooling to retain the desired microstructure.
Forging
The forging process involves heating the Super Duplex 2507 material to a temperature between 1050°C and 1150°C and then shaping it using mechanical forces. This process enhances the mechanical properties and ensures uniform grain structure.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050 - 1100 | Water | Increase hardness and strength |
| Tempering | 650 - 750 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Eliminate residual stresses |
The combination of these processes ensures that Super Duplex 2507 flanges exhibit excellent corrosion resistance and mechanical properties, making them suitable for demanding industrial applications.
