Manufacturing Process & Heat Treatment of Super Duplex Flanges
Annealing
Annealing of super duplex flanges involves heating the material to a temperature range of approximately 1020°C to 1100°C, followed by controlled cooling. This process helps to relieve stresses, improve ductility, and homogenize the microstructure, enhancing the overall mechanical properties of the flanges.
Forging
Forging of super duplex flanges is conducted at elevated temperatures, typically between 1100°C and 1200°C. This process involves shaping the material through compressive forces, which enhances the material's strength and toughness by refining the grain structure and reducing internal defects.
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 stress |
| Solution Treatment | 1050 - 1100 | Water | Dissolve precipitates and improve corrosion resistance |
The manufacturing and heat treatment processes for super duplex flanges are critical in achieving the desired mechanical properties and corrosion resistance, making them suitable for various industrial applications.
