Manufacturing Process & Heat Treatment of Super Duplex Flanges
Annealing
Annealing of super duplex flanges involves heating the material to a temperature range of 1000°C to 1100°C, followed by controlled cooling. This process reduces internal stresses, enhances ductility, and improves the overall microstructure of the flanges, making them more suitable for further machining and fabrication.
Forging
The forging process for super duplex flanges is conducted at temperatures between 1050°C and 1200°C. This process involves shaping the material through mechanical deformation, which refines the grain structure and enhances the mechanical properties, resulting in stronger and more durable flanges.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness while maintaining hardness |
| Stress Relieving | 400 - 600 | Air | Eliminate residual stresses from machining |
The combination of these manufacturing processes and heat treatments ensures that super duplex flanges achieve optimal mechanical properties, making them suitable for high-pressure and high-temperature applications in various industries.
