Manufacturing Process & Heat Treatment of SS 347 Nut Bolt
Annealing
Annealing of SS 347 nut bolts is conducted to relieve internal stresses, improve ductility, and enhance the overall mechanical properties. The process involves heating the material to a temperature of around 1050-1100°C, followed by controlled cooling.
Forging
The forging process for SS 347 nut bolts is performed at elevated temperatures, typically between 950-1200°C. This hot working process enhances the strength and toughness of the material, ensuring a refined grain structure and improved mechanical properties.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil or Water | To increase hardness and strength |
| Tempering | 600-750 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 600-700 | Air | To minimize residual stresses |
The combination of these processes ensures that SS 347 nut bolts possess optimal mechanical properties and performance characteristics for various industrial applications.
