Manufacturing Process & Heat Treatment of SS 304
Annealing
Annealing of SS 304 involves heating the steel to a temperature range of 1010-1120°C followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the material.
Forging
Forging of SS 304 is typically performed at elevated temperatures between 1050-1200°C. This process improves the grain structure and mechanical properties of the steel while ensuring dimensional accuracy and strength in the final product.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1010-1120 | Water or Oil | To increase hardness and strength |
| Tempering | 400-700 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 600-800 | Air | To relieve residual stresses from manufacturing |
The combination of these manufacturing and heat treatment processes ensures that SS 304 products meet the stringent requirements for strength, durability, and corrosion resistance, making them suitable for a wide range of industrial applications.
