Core Manufacturing Process of Ultra-Thin Stainless Steel Sheet
1. Precision Cold Rolling
Ultra-thin stainless steel sheets are primarily produced through multi-pass cold rolling.
- Initial thickness reduction from hot-rolled coils
- Use of high-precision rolling mills
- Thickness controlled within micrometer tolerances
Key challenges:
- Thickness deviation control
- Roll gap stability
- Surface defect prevention
2. Intermediate Annealing Process
Annealing is required between rolling passes to restore ductility and prevent cracking.
Typical process:
- Heating to recrystallization temperature
- Short holding time due to thin material
- Controlled cooling to maintain uniform structure
Effects:
- Eliminates work hardening
- Improves elongation
- Stabilizes microstructure
3. Final Annealing and Surface Treatment
Final annealing determines the mechanical properties and surface condition.
Common methods:
- Recuit brillant (BA) for ultra-clean surface
- Protective atmosphere to avoid oxidation
- Precise tension control to prevent wrinkling
Slitting and Cutting Technology
Traitement 0.05 mm stainless steel requires non-deforming cutting methods.
Refendage
