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 process involves heating the material to a temperature of approximately 1020-1100°C, followed by controlled cooling. This treatment enhances the microstructure, ensuring optimal performance in corrosive environments.
Forging
Forging of Super Duplex 2507 flanges is performed at elevated temperatures, typically between 1100-1200°C. This process enhances the mechanical properties of the steel, providing improved strength and toughness. The forged flanges are then subjected to further processing to achieve the desired dimensions and surface finish.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050-1150 | Oil | Increase hardness and strength |
| Tempering | 300-600 | Air | Reduce brittleness and enhance toughness |
| Stress Relieving | 300-350 | Air | Minimize residual stresses |
The combination of these manufacturing and heat treatment processes ensures that Super Duplex 2507 flanges meet the stringent requirements for high strength and corrosion resistance in various industrial applications.
