Manufacturing Process & Heat Treatment of Super Duplex Flanges
Annealing
Annealing of super duplex flanges involves heating the material to a temperature of approximately 1020°C to 1100°C, followed by controlled cooling. This process is essential for relieving internal stresses, improving ductility, and homogenizing the microstructure, which enhances overall corrosion resistance and mechanical properties.
Forging
The forging process for super duplex flanges is conducted at high temperatures, typically ranging from 1100°C to 1200°C. This method involves shaping the flanges through deformation under compressive forces, leading to improved strength and toughness due to the refined grain structure. The forged flanges are then allowed to cool slowly to room temperature.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and enhance toughness |
| Solution Treatment | 1050 - 1150 | Water | Optimize corrosion resistance and mechanical properties |
The combined processes of forging, hardening, and tempering ensure that super duplex flanges achieve the desired mechanical properties and corrosion resistance, making them suitable for various industrial applications, including oil and gas, chemical processing, and marine environments.
