Manufacturing Process & Heat Treatment of SS 347 Hex Bolt
Annealing
Annealing of SS 347 hex bolts involves heating the material to a temperature of approximately 1050°C to 1150°C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance machinability. The slow cooling process is typically done in a furnace, reducing the risk of cracking and ensuring uniform properties throughout the material.
Forging
The forging process for SS 347 hex bolts is conducted at elevated temperatures, usually between 900°C and 1200°C. This involves shaping the metal through compressive forces, which improves its strength and structural integrity. The forging process also helps to refine the grain structure of the steel, resulting in enhanced mechanical properties.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040 - 1100 | Oil | Increase hardness and strength |
| Tempering | 400 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300 - 400 | Air | Eliminate residual stresses |
The combination of these manufacturing processes and heat treatments ensures that SS 347 hex bolts meet the stringent requirements for strength, durability, and corrosion resistance, making them suitable for various industrial applications.
