Manufacturing Process & Heat Treatment of Super Duplex 2507 Flanges
Annealing
Annealing of Super Duplex 2507 flanges is performed to relieve internal stresses and improve ductility. The process involves heating the material to a temperature range of 1020°C to 1100°C, followed by a controlled cooling process. This treatment enhances the mechanical properties and allows for better machining characteristics.
Forging
The forging of Super Duplex 2507 flanges is carried out using hot working techniques. The material is heated to approximately 1150°C to 1200°C and then shaped under high pressure to achieve the desired dimensions. This process optimizes the grain structure, resulting in improved strength and toughness of the final product.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water | To increase hardness and strength |
| Tempering | 600 - 800 | Air | To reduce brittleness and enhance toughness |
| Stabilization | 800 - 900 | Air | To enhance corrosion resistance |
The combination of these processes ensures that Super Duplex 2507 flanges meet the stringent requirements for high strength and corrosion resistance in various industrial applications.
