Manufacturing Process & Heat Treatment of SS 321 Flanges
Annealing
Annealing of SS 321 flanges is performed to relieve internal stresses and improve ductility. The flanges are heated to a temperature range of 900-1100°C and held for a specified time before being cooled slowly in a furnace. This process enhances the overall mechanical properties and corrosion resistance of the material.
Forging
Forging of SS 321 flanges is conducted at elevated temperatures, typically between 950-1200°C. This process involves shaping the material through compressive forces, which improves the grain structure and mechanical properties. The forged flanges undergo further machining to achieve the desired dimensions and surface finish.
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 | 600-700 | Air | Minimize residual stresses |
The careful combination of manufacturing processes and heat treatment ensures that SS 321 flanges meet the stringent quality standards required for various industrial applications, providing excellent performance and longevity in service.
