0.3 Lamiera di acciaio da mm

0.3 Lamiera di acciaio da mm

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

Descrizione

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, elettronica, automotive interiors, elettrodomestici, e applicazioni decorative. At this thickness, 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 Rolling Process for 0.3 Lamiera di acciaio inossidabile da mm

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

Principali fasi di elaborazione

1. Preparazione del coil laminato a caldo

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

2. Cold Rolling Reduction

Fare un passo	Descrizione
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. Pickling and Surface Cleaning

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

5. Opzioni di finitura superficiale

Tipo di finitura	Descrizione	Applicazione
2B Fine	Liscio, superficie opaca	Uso industriale
Finitura BA	Bright annealed surface	Applicazioni decorative
Finitura a specchio	Superficie altamente riflettente	Decorazione d'interni
Finitura spazzolata	Linear texture surface	Pannelli degli elettrodomestici

Key Processing Characteristics of 0.3 Lamiera di acciaio inossidabile da mm

At this thickness, the material requires careful handling.

1. High Precision Cutting

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

2. Piegatura e formatura
