Manufacturing Process & Heat Treatment of SS 347 Hex Bolt
Annealing
The annealing process for SS 347 hex bolts involves heating the bolts to a temperature of approximately 1000-1100°C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the bolts, making them suitable for various industrial applications.
Forging
Forging of SS 347 hex bolts is performed at high temperatures, typically between 950-1200°C. The material is shaped using mechanical or hydraulic presses, ensuring uniform density and improved strength. This process enhances the structural integrity of the bolts, making them resistant to fatigue and stress.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Oil or Water | To increase hardness and strength |
| Tempering | 600-700 | Air | To reduce brittleness and improve toughness |
| Stress Relief | 300-500 | Air | To relieve residual stresses from the hardening process |
The combination of these manufacturing and heat treatment processes ensures that SS 347 hex bolts possess superior mechanical properties and corrosion resistance, making them ideal for demanding applications in various industries.
