Manufacturing Process & Heat Treatment of SS 347 Hex Bolt
Annealing
Annealing of SS 347 hex bolts involves heating the material to a temperature range of 1000-1100°C, followed by controlled cooling. This process reduces internal stresses, enhances ductility, and improves machinability, making the material easier to work with during subsequent manufacturing processes.
Forging
The forging process for SS 347 hex bolts is carried out at elevated temperatures, typically between 900-1200°C. This method involves shaping the metal by applying compressive forces, which improves the mechanical properties of the bolts by refining the grain structure and increasing strength.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040-1150 | Oil or Water | To increase hardness and strength by transforming the microstructure to martensite. |
| Tempering | 400-800 | Air | To reduce brittleness and relieve stresses introduced during hardening. |
| Final Heat Treatment | 600-700 | Air | To further enhance toughness and ductility, ensuring optimal performance in service. |
The combination of these processes ensures that SS 347 hex bolts possess high strength, excellent corrosion resistance, and durability, making them suitable for various industrial applications.
