Manufacturing Process & Heat Treatment of Super Duplex Flanges
Annealing
Annealing of super duplex flanges involves heating the material to a temperature range of 1020°C to 1100°C, followed by controlled cooling. This process helps in relieving residual stresses and improving ductility, ensuring better performance during service.
Forging
Forging of super duplex flanges is carried out at elevated temperatures, typically between 1100°C and 1250°C. This process enhances the mechanical properties of the material by refining the grain structure, resulting in improved strength and toughness.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 300 - 600 | Air | Reduce brittleness and relieve stresses |
| Final Heat Treatment | 1000 - 1100 | Water | Ensure optimal microstructure for corrosion resistance |
The combination of these processes ensures that super duplex flanges meet the stringent requirements for high strength and corrosion resistance, making them suitable for various industrial applications.
