Annealing
Annealing of Duplex S32205 flanges is conducted at temperatures ranging from 1020°C to 1100°C. This process helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the material.
Forging
The forging process for Duplex S32205 involves heating the steel to a temperature between 1150°C and 1250°C. During forging, the material is shaped into flanges using hydraulic presses or hammers, ensuring a fine grain structure and improved strength.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300 - 500 | Air | Eliminate residual stresses |
