Manufacturing Process & Heat Treatment of Duplex 2101 Flanges
Annealing
Annealing of Duplex 2101 flanges is conducted to relieve internal stresses and improve ductility. The flanges are heated to a temperature range of 950-1050°C and held for a specific duration before being slowly cooled in air. This process enhances the microstructure, ensuring optimal performance in various applications.
Forging
The forging process for Duplex 2101 flanges involves hot working the alloy at temperatures between 900-1200°C. This method enhances the grain structure and mechanical properties, providing superior strength and durability. The forged flanges are then subjected to machining to meet precise dimensional tolerances.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil or Water | Increase hardness and strength |
| Tempering | 600-800 | Air | Reduce brittleness and relieve stresses |
| Stress Relieving | 300-500 | Air | Minimize residual stresses post-fabrication |
The combination of these processes ensures that Duplex 2101 flanges are manufactured to meet stringent international standards, offering excellent corrosion resistance and mechanical properties suitable for diverse industrial applications.
