Manufacturing Process & Heat Treatment of SS 347 Flanges
Annealing
Annealing of SS 347 flanges involves heating the material to a temperature range of 1000°C to 1100°C, followed by slow cooling. This process helps to relieve internal stresses, improve ductility, and enhance the overall structural integrity of the flanges.
Forging
Forging of SS 347 flanges is performed at elevated temperatures, typically between 900°C and 1200°C. This process improves the mechanical properties of the flanges by refining the grain structure, resulting in improved strength and toughness.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050 - 1100 | Oil | To increase hardness and strength |
| Tempering | 600 - 800 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 400 - 600 | Air | To alleviate residual stresses from manufacturing |
The manufacturing and heat treatment processes for SS 347 flanges are critical to ensuring that the final products meet the required specifications for strength, durability, and corrosion resistance, making them suitable for various industrial applications.
