0.3 mm tôle d'acier

0.3 mm tôle d'acier

0.3 mm cold rolled stainless steel sheet is an ultra-thin metal material produced through precise cold rolling, recuit, and surface finishing processes. It is commonly available in grades such as 304, 316, 301, et 430, offering a balance of corrosion resistance, force, et la formabilité.

Description

UN 0.3 mm steel sheet usually refers to cold rolled stainless steel sheet in ultra-thin gauge form. It is widely used in precision manufacturing, électronique, automotive interiors, appareils électroménagers, et applications décoratives. A cette épaisseur, the material combines good corrosion resistance with high surface quality, but also requires controlled processing due to its thin structure.

Common Grades of 0.3 mm Cold Rolled Stainless Steel Sheet

Cold rolled stainless steel sheets at 0.3 mm thickness are commonly produced in austenitic and ferritic grades depending on application requirements.

Grade	Caractéristiques	Application
304	Excellente résistance à la corrosion, bonne formabilité	General industrial and decorative use
304L	Version bas carbone, meilleure soudabilité	Structures soudées
316	Haute résistance à la corrosion, grade marin	Chemical and marine environments
301	High strength after cold working	Ressorts, pièces de précision

2. Acier inoxydable ferritique

Grade	Caractéristiques	Application
430	Magnétique, bonne résistance à la corrosion	Appareils électroménagers, décoration
409	Résistant à la chaleur, rentable	Systèmes d'échappement automobiles

3. Other Special Grades

Grade	Caractéristiques	Application
201	Teneur en nickel inférieure, cost-efficient	Decorative and general use
321	Stabilized with titanium	Applications à haute température

Cold Rolling Process for 0.3 mm tôle d'acier inoxydable

Cold rolling is the key process used to achieve 0.3 mm thickness with high precision and smooth surface quality.

Principales étapes de traitement

1. Préparation des bobines laminées à chaud

Initial stainless steel slab is hot rolled into coil form
Surface scale is removed before further processing

2. Réduction du laminage à froid

Étape	Description
Multi-pass rolling	Thickness gradually reduced to 0.3 mm
High pressure rolling	Improves surface finish and density
Precision control	Ensures thickness uniformity

Cold rolling significantly improves mechanical strength and surface smoothness.

3. Annealing Process

Heat treatment is applied to relieve internal stress
Restores ductility for further processing
Improves formability of ultra-thin sheet

4. Décapage et nettoyage des surfaces

Removes oxidation and surface impurities
Produces clean metallic surface
Prepares sheet for final finishing

5. Options de finition de surface

Type de finition	Description	Application
2Finition B	Lisse, surface mate	Usage industriel
Finition BA	Bright annealed surface	Applications décoratives
Finition miroir	Surface hautement réfléchissante	Décoration d'intérieur
Finition brossée	Linear texture surface	Panneaux d'appareils

Key Processing Characteristics of 0.3 mm tôle d'acier inoxydable

A cette épaisseur, the material requires careful handling.

1. High Precision Cutting

Laser cutting is commonly used
Shearing must control edge deformation
Burr control is critical

2. Pliage et formage

Small bending radius required
Springback effect must be compensated
Thin sheet may wrinkle if unsupported

3. Stamping and Punching

Requires fine tooling
Low forming pressure recommended
Die surface must be smooth

4. Performances de soudage

TIG and laser welding commonly used
Heat input must be controlled
Thin sheet is prone to distortion
