Manufacturing Process & Heat Treatment of SS 347 Flanges
Annealing
Annealing is a heat treatment process that involves heating the SS 347 flanges to a temperature of approximately 1050-1100°C, followed by a controlled cooling process. This treatment is crucial for relieving internal stresses, enhancing ductility, and improving the material's machinability. The result is a more uniform microstructure, which contributes to the overall performance and longevity of the flanges in various applications.
Forging
Forging of SS 347 flanges is done through a hot working process where the steel is heated to a temperature of about 1200°C and then shaped under mechanical pressure. This process improves the grain structure of the material, increases its strength, and ensures dimensional accuracy. The forged flanges exhibit superior mechanical properties and are suitable for high-stress applications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Oil | To increase hardness and strength |
| Tempering | 600-800 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 500-600 | Air | To alleviate internal stresses from welding and machining |
The manufacturing and heat treatment processes applied to SS 347 flanges ensure that they meet the required specifications for high-performance applications, offering excellent resistance to corrosion and oxidation, making them ideal for use in various industries including petrochemical and power generation.
