The On-Line Bright Annealing is a controlled process of heating between 1040°C-1080°C, and then cooling it with quenching water. We use 99.999% pure hydrogen for high quality surface finish.
Advantages
- Reduce the hardness of Stainless Steel tubes, improve the plasticity, to facilitate cutting machining and cold deformation.
- Fine grains and homogeneous steel organization and composition, to improve the performance of Stainless steel tubes.
- Remove the residual internal stress in Stainless steel tubes, to prevent deformation and cracking.
| Sr.No. | BRIGHT ANNEALING | SOLUTION ANNEALING(Annealing & Pickling) |
|---|---|---|
| 1. | Under Reducing Atmosphere [ N2 & H blanketing] | Under Oxidation Atmosphere [ presence of O2 ] |
| 2. | No oxidation possibility | Oxidation in part of process |
| 3. | No chemical effluents, Green Process | Highly polluting process with highly Polluting effluents. Not a green process. |
| 4. | No Oxidation, No pickling necessary. | Pickling necessary to remove oxidation formed during Annealing. |
| 5. | Smooth surface finish can reduce Contamination | Pitting and rough surface finish can Create contamination. |
| Bright Annealing is a Non-Oxidation, Clean & Green Process. | ||
