Manufacturing Process & Heat Treatment of SS 347
Annealing
Annealing of SS 347 is performed to relieve internal stresses and improve the ductility of the material. The process involves heating the steel to a temperature of around 1050-1100°C, followed by controlled cooling. This treatment enhances the material's toughness and prepares it for subsequent processing.
Forging
Forging of SS 347 involves shaping the material through compressive forces applied using hammers or presses. The forging process typically occurs at elevated temperatures (around 1150-1250°C) to ensure the material's malleability. This method improves the grain structure, resulting in enhanced mechanical properties and overall strength of the nut and bolt products.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Oil or Air | To increase hardness and strength |
| Tempering | 600-750 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 300-500 | Air | To relieve residual stresses from the manufacturing process |
The combination of these manufacturing processes and heat treatments ensures that SS 347 nut and bolt products meet the stringent requirements for strength, durability, and corrosion resistance in various industrial applications.
