Manufacturing Process & Heat Treatment of Stainless Steel 17-4ph Round Bar
Annealing
Annealing of 17-4 PH stainless steel is typically performed at a temperature range of 1040-1120 °C (1900-2050 °F) followed by air cooling. This process helps to relieve internal stresses, improve ductility, and enhance formability, making the material easier to work with during subsequent manufacturing operations.
Forging
Forging of 17-4 PH stainless steel is carried out at elevated temperatures, generally between 900-1200 °C (1650-2200 °F). This hot forging process enhances the mechanical properties and ensures a fine grain structure, which contributes to the overall strength and toughness of the final product.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040-1120 | Oil or Water | To increase hardness and strength |
| Tempering | 480-620 | Air | To reduce brittleness and improve toughness |
| Stabilization | 480-600 | Air | To enhance corrosion resistance and dimensional stability |
