Manufacturing Process & Heat Treatment of SS 304 Flanges
Annealing
Annealing of SS 304 flanges is performed to relieve internal stresses and improve the ductility of the material. The flanges are heated to a temperature range of 1020-1120°C and then cooled slowly in air. This process enhances the corrosion resistance and overall mechanical properties of the flanges, making them suitable for various applications in industries such as chemical processing and food manufacturing.
Forging
The forging of SS 304 flanges involves shaping the metal through compressive forces, typically performed at elevated temperatures between 1100-1200°C. This process refines the grain structure, resulting in improved strength and toughness. Once forged, the flanges are further worked to achieve the desired dimensions and surface finish.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040-1100 | Water/Oil | Increase hardness and strength |
| Tempering | 300-600 | Air | Reduce brittleness and relieve stresses |
| Stress Relieving | 600-700 | Air | Eliminate residual stresses |
The combination of these processes ensures that SS 304 flanges meet the stringent quality and performance standards required in various industrial applications.
