Manufacturing Process & Heat Treatment of Duplex 2101 Round Bar
Annealing
Annealing of Duplex 2101 round bars is conducted at a temperature range of 1020-1100°C to relieve internal stresses and improve ductility. This process involves heating the material uniformly, followed by controlled cooling, which enhances the microstructure and prepares the steel for further processing.
Forging
Forging of Duplex 2101 involves shaping the material through deformation at elevated temperatures, typically between 1000-1200°C. This process enhances the mechanical properties by refining the grain structure and ensuring uniformity in the material, resulting in a stronger and more durable round bar.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Water or Oil | Increase hardness and strength |
| Tempering | 400-600 | Air | Reduce brittleness and relieve stresses |
| Stabilization | 800-900 | Air | Enhance corrosion resistance and toughness |
The combination of these processes ensures that Duplex 2101 round bars possess excellent mechanical properties and resistance to corrosion, making them suitable for various industrial applications.
