Manufacturing Process & Heat Treatment of Duplex Flanges
Annealing
Annealing of duplex flanges is performed at temperatures between 1020°C and 1100°C. This process helps to relieve internal stresses, improve ductility, and refine the microstructure, ensuring a uniform phase distribution of austenite and ferrite.
Forging
Forging of duplex flanges involves heating the steel to approximately 1150°C to 1250°C, followed by mechanical deformation. This process enhances the mechanical properties of the material, providing improved strength and toughness through grain refinement.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water or Oil | To increase hardness and strength by transforming the microstructure to martensite. |
| Tempering | 600 - 800 | Air | To reduce brittleness and improve toughness while maintaining hardness. |
| Stress Relieving | 300 - 500 | Air | To alleviate residual stresses from previous manufacturing processes. |
The combination of these processes ensures that duplex flanges achieve optimal mechanical properties, making them suitable for various industrial applications, including oil and gas, marine, and chemical processing.
