Manufacturing Process & Heat Treatment of Duplex 2207 Round Bar
Annealing
Annealing of Duplex 2207 round bars is performed to relieve internal stresses and improve ductility. The bars are heated to a temperature range of 1020-1100 °C and held for a sufficient time to allow for homogenization of the microstructure, followed by controlled cooling to room temperature.
Forging
Forging of Duplex 2207 is conducted at temperatures between 1100-1300 °C. This process enhances the mechanical properties of the material by refining the grain structure and ensuring uniformity. The forged bars are then subjected to cooling processes that allow for the development of the desired microstructure.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Water or Oil | Increase hardness and strength |
| Tempering | 400-600 | Air | Reduce brittleness and adjust hardness |
| Stabilization | 900-1000 | Air | Enhance corrosion resistance |
The combined manufacturing and heat treatment processes ensure that Duplex 2207 round bars achieve optimal mechanical properties and corrosion resistance, making them suitable for various industrial applications.
