Manufacturing Process & Heat Treatment of SS 347 Hex Bolt
Annealing
Annealing of SS 347 hex bolts is performed to relieve internal stresses and improve ductility. The bolts are heated to a temperature of approximately 1050°C to 1100°C and held for a specified duration, followed by slow cooling. This process enhances the machinability of the material and prepares it for subsequent processing.
Forging
Forging of SS 347 hex bolts involves shaping the raw material through deformation under high pressure. The process is conducted at elevated temperatures, typically around 900°C to 1200°C, which allows the material to become more malleable. This results in improved mechanical properties and uniform grain structure, essential for high-performance applications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Oil or Water | To increase hardness and strength of the bolts. |
| Tempering | 600 - 800 | Air | To reduce brittleness and improve toughness. |
| Stress Relieving | 300 - 400 | Air | To eliminate residual stresses from the manufacturing process. |
The combination of these processes ensures that SS 347 hex bolts achieve optimal mechanical properties and performance characteristics, making them suitable for various industrial applications.
