0.2 mm d'épaisseur de tôle d'acier inoxydable
UN 0.2 mm stainless steel sheet is an ultra-thin metal sheet that sits between standard stainless steel sheets and stainless steel foil. Compared with foil, it offers significantly better strength, stabilité, and processing capability while still maintaining a very thin profile.
En résumé:
- Stainless steel foil = extremely thin, flexible, non-structural material
- 0.2 mm stainless steel sheet = ultra-thin but still structurally usable sheet material
- Description
UN 0.2 tôle d'acier inoxydable de mm d'épaisseur is considered an ultra-thin stainless steel product widely used in precision applications, électronique, composants automobiles, panneaux décoratifs, and filtration systems. At this thickness level, stainless steel is close to the boundary between feuille mince et metal foil, so understanding the difference between 0.2 mm sheet and stainless steel foil is important for material selection.
Qu'est-ce que 0.2 mm tôle d'acier inoxydable?
UN 0.2 mm stainless steel sheet is a rolled stainless steel product with a thickness of 0.2 millimètres. It still maintains a continuous sheet structure with enough strength for forming, coupe, and light stamping.
It is commonly produced in grades such as:
- 304 acier inoxydable
- 316 acier inoxydable
- 301 acier inoxydable
- 430 acier inoxydable
Différence entre 0.2 mm Stainless Steel Sheet and Stainless Steel Foil
Although both are very thin, they are defined differently based on thickness, résistance mécanique, and application.
1. Thickness Classification
| Type de matériau | Plage d'épaisseur |
|---|---|
| Stainless Steel Foil | ≤ 0.05 mm (very thin) |
| Ultra-thin Stainless Sheet | 0.05 – 0.5 mm |
| 0.2 mm feuille inoxydable | 0.2 mm |
| Standard Stainless Sheet | ≥ 0.5 mm |
0.2 mm is generally classified as ultra-thin sheet, not foil.
2. Résistance mécanique
| Propriété | 0.2 mm Feuille | Stainless Steel Foil |
|---|---|---|
| Force | Modéré | Très faible |
| Rigidity | Can maintain shape | Easily deformed |
| Load Capacity | Light structural use | No structural use |
| Manutention | Requires tooling | Can tear easily |
0.2 mm sheet still has usable structural integrity, while foil is mainly non-structural.
3. Capacité de traitement
| Processus | 0.2 mm Feuille | Stainless Steel Foil |
|---|---|---|
| Coupe | Laser, shear cutting | Manual tearing or precision cutting |
| Pliage | Easy micro bending | Very limited |
| Estampillage | Possible light stamping | Not suitable |
| Soudage | Possible (thin welding) | Rarely used |
4. Différences d'application
Stainless Steel Foil Applications
- Thermal insulation layers
- Battery and electronic shielding
- Food packaging
- Flexible heat shields
- Laboratory materials
0.2 mm Stainless Steel Sheet Applications

5. Surface and Durability
| Fonctionnalité | 0.2 mm Feuille | Stainless Steel Foil |
|---|---|---|
| Surface Stability | Bien | Très délicat |
| Scratch Resistance | Modéré | Faible |
| Résistance à la corrosion | Excellent (304/316) | Excellent |
| Service Life | Long-term use | Short to medium term |
Nuances courantes d'acier inoxydable pour 0.2 mm Feuille
| Grade | Caractéristiques | Application |
|---|---|---|
| 304 | Résistance générale à la corrosion, bonne formabilité | Industrial and decorative use |
| 316 | Résistance améliorée à la corrosion (grade marin) | Chemical and marine environments |
| 301 | High strength after cold working | Composants de précision |
| 430 | Ferritic stainless, magnétique | Decorative and appliance use |
Avantages de 0.2 mm tôle d'acier inoxydable
| Fonctionnalité | Avantage |
|---|---|
| Ultra-thin structure | Suitable for precision applications |
| Good strength retention | More stable than foil |
| Excellente résistance à la corrosion | Longue durée de vie |
| Good formability | Suitable for bending and stamping |
