Manufacturing Process & Heat Treatment of SS 347
Annealing
Annealing of SS 347 involves heating the material to a temperature of approximately 1050°C to 1100°C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and refine the microstructure for enhanced mechanical properties.
Forging
The forging process for SS 347 is typically conducted at temperatures between 900°C and 1200°C. This hot working process enhances the strength and toughness of the material by refining the grain structure and improving its overall integrity.
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 |
| Stress Relieving | 300 - 500 | Air | Minimize residual stresses |
The combination of these processes ensures that SS 347 nuts and bolts meet the high standards required for durability and performance in various industrial applications.
