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 controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the steel, ensuring better performance in high-temperature applications.
Forging
The forging process for SS 347 flanges is conducted at elevated temperatures, typically between 1100°C and 1200°C. This hot working process enhances the grain structure of the steel, resulting in improved strength and toughness. The flanges are shaped and formed through various techniques such as open-die or closed-die forging, depending on the design requirements.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1030 - 1100 | Oil or Water | Increase hardness and strength |
| Tempering | 600 - 750 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Minimize residual stresses |
The comprehensive manufacturing and heat treatment processes of SS 347 flanges ensure that the final product meets the stringent requirements of various industrial applications, providing reliability and durability in service.
