Manufacturing Process & Heat Treatment of Super Duplex 2507 Flanges
Annealing
Annealing of Super Duplex 2507 involves heating the material to a temperature range of 1020°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
The forging of Super Duplex 2507 flanges is typically performed at temperatures between 1100°C and 1200°C. This hot working process enhances the strength and toughness of the material while refining its microstructure, resulting in improved performance under high pressure and temperature conditions.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil or Water | Increase hardness and strength |
| Tempering | 300 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 800 | Air | Minimize residual stresses |
The combination of these processes ensures that Super Duplex 2507 flanges meet the stringent requirements for corrosion resistance and mechanical strength, making them suitable for various high-performance applications in demanding environments.
