0.3 mm Stahlblech

0.3 mm Stahlblech

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

Beschreibung

A 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, Elektronik, automotive interiors, Haushaltsgeräte, und dekorative Anwendungen. Bei dieser Dicke, the material combines good corrosion resistance with high surface quality, but also requires controlled processing due to its thin structure.

Cold Rolling Process for 0.3 mm Edelstahlblech

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

Main Processing Steps

1. Vorbereitung warmgewalzter Coils

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

2. Kaltwalzreduktion

Schritt	Beschreibung
Multi-pass rolling	Thickness gradually reduced to 0.3 mm
High pressure rolling	Improves surface finish and density
Präzise Steuerung	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. Beizen und Oberflächenreinigung

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

5. Optionen zur Oberflächenveredelung

Finish-Typ	Beschreibung	Anwendung
2B Fertig	Glatt, matte Oberfläche	Industrielle Nutzung
BA-Abschluss	Bright annealed surface	Dekorative Anwendungen
Hochglanzpoliert	Hochreflektierende Oberfläche	Innenausstattung
Gebürstetes Finish	Linear texture surface	Gerätepaneele

Key Processing Characteristics of 0.3 mm Edelstahlblech

Bei dieser Dicke, the material requires careful handling.

1. High Precision Cutting

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

2. Biegen und Formen

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. Welding Performance

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