Heat Treatment
Heat Treatment
- Solution Annealing: Heat 303 stainless steel to about 1010°C to 1120°C and then cool rapidly (usually water quenching or air cooling). This process is used to dissolve carbides and restore the corrosion resistance and toughness of the material.
- Stress Relieving Annealing: Usually carried out at a temperature of about 200°C to 400°C, heating to remove internal stress after processing or welding, followed by slow cooling.
- Annealing: Heat the tubing to 800°C to 900°C and then cool slowly. This process is mainly used to soften the material and improve processing properties.
- Precipitation Hardening, Quenching and Tempering: 303 stainless steel is an austenitic stainless steel, so these treatments are not applicable.
Characteristic
Characteristic
- Excellent machinability: 303 stainless steel tubing have greatly improved the machinability of the material due to the addition of sulfur or selenium, making them very suitable for applications that require frequent machining.
- Good corrosion resistance: 303 stainless steel tubes show good corrosion resistance in most mild to moderately corrosive environments, especially in dry and neutral environments.
- High strength and durability: 303 stainless steel tubing have high strength and durability, suitable for applications with medium strength requirements.
- Smooth surface treatment: 303 stainless steel tubing can obtain a smooth surface through polishing and other surface treatments, suitable for applications that require good appearance and surface finish.
- Suitable for lower temperature applications: 303 stainless steel performs well at lower temperatures and can maintain its mechanical properties.
