Manufacturing Process & Heat Treatment of SS 347 Flanges
Annealing
Annealing of SS 347 flanges is performed to relieve internal stresses and improve the material's ductility. This process involves heating the flanges to a temperature range of 1050°C to 1150°C, followed by controlled cooling. The result is a more uniform microstructure, which enhances the overall mechanical properties of the flanges.
Forging
The forging process for SS 347 flanges involves shaping the material through mechanical deformation under high temperature. This is typically done at temperatures between 900°C and 1200°C. Forging improves the strength and toughness of the flanges by refining the grain structure and eliminating any porosity.
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 |
| Stabilization | 850 - 950 | Air | Prevent sensitization and improve corrosion resistance |
The combination of these processes ensures that SS 347 flanges achieve optimal mechanical properties and resistance to corrosion, making them suitable for various industrial applications.
