Manufacturing Process & Heat Treatment of SS 347 Sheet and Coils
Annealing
Annealing of SS 347 involves heating the material to a temperature range of 1010-1120°C, followed by controlled cooling. This process is essential to relieve internal stresses, improve ductility, and refine the microstructure, resulting in enhanced workability and corrosion resistance.
Forging
Forging of SS 347 is typically performed at elevated temperatures between 1100-1200°C. This hot working process enhances the material's mechanical properties by aligning the grain structure, providing improved strength and toughness while allowing for complex shapes to be formed.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040-1100 | Oil or Water | Increase hardness and strength |
| Tempering | 600-800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600-700 | Air | Eliminate residual stresses |
