Manufacturing Process & Heat Treatment of SS 347 Flanges
Annealing
Annealing of SS 347 flanges involves heating the material to a temperature between 1000°C and 1100°C, followed by controlled cooling. This process helps in relieving internal stresses, improving ductility, and enhancing the overall mechanical properties of the stainless steel.
Forging
Forging of SS 347 flanges is carried out at high temperatures, typically around 1150°C to 1250°C. This process involves shaping the material through compressive forces, which improves the grain structure and mechanical strength of the flanges, making them more suitable for high-pressure applications.
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 |
| Solution Treatment | 1050 - 1150 | Water | Dissolve carbides and improve corrosion resistance |
The proper manufacturing and heat treatment processes are essential to ensure that SS 347 flanges meet the required specifications and performance standards, making them ideal for various industrial applications.
