Manufacturing Process & Heat Treatment of SS 321 Flanges
Annealing
Annealing of SS 321 flanges is performed to relieve internal stresses and improve ductility. The process involves heating the material to a temperature range of 950°C to 1100°C, followed by controlled cooling. This results in a refined microstructure and enhanced mechanical properties, making the flanges more suitable for high-temperature applications.
Forging
Forging of SS 321 flanges is conducted using hot working techniques. The steel is heated to approximately 1200°C and then shaped using mechanical or hydraulic presses. This process enhances the strength and toughness of the flanges by aligning the grain structure, resulting in superior performance under pressure and temperature variations.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 700 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Eliminate residual stresses |
The combination of these manufacturing and heat treatment processes ensures that SS 321 flanges meet the rigorous demands of industrial applications, providing excellent corrosion resistance and mechanical performance in various environments.
