Manufacturing Process & Heat Treatment of Super Duplex Flanges
Annealing
The annealing process for super duplex flanges involves heating the material to a temperature range of 1020°C to 1100°C, followed by a controlled cooling process. This treatment helps to relieve internal stresses, enhances ductility, and improves the overall mechanical properties of the flanges.
Forging
Forging of super duplex flanges is performed at high temperatures, typically between 1100°C and 1200°C. The process involves shaping the metal through compressive forces, which improves its strength and structural integrity. This method is essential for producing flanges with superior mechanical properties and dimensional accuracy.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050 - 1150 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300 - 600 | Air | Eliminate residual stresses |
The combination of these manufacturing and heat treatment processes ensures that super duplex flanges meet the stringent requirements for strength, corrosion resistance, and durability in various industrial applications.
