Manufacturing Process & Heat Treatment of SS 347H Flanges
Annealing
Annealing of SS 347H flanges is performed to relieve internal stresses and enhance ductility. The process involves heating the flanges to a temperature range of 1000°C to 1100°C, followed by a slow cooling process. This treatment helps in reducing hardness and improving workability, making the material suitable for further machining and forming operations.
Forging
Forging of SS 347H flanges is conducted at elevated temperatures, typically between 1100°C and 1200°C. This process improves the mechanical properties of the material by refining the grain structure and enhancing strength. The forged flanges are then subjected to a controlled cooling process to maintain their integrity and dimensional accuracy.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050 - 1150 | Water or Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and relieve stresses |
| Stress Relieving | 600 - 700 | Air | Enhance dimensional stability |
The combination of these manufacturing processes and heat treatments ensures that SS 347H flanges meet the stringent requirements for high-temperature applications and provide excellent corrosion resistance.
