0.3 mm Lembaran Keluli

0.3 mm Lembaran Keluli

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

Penerangan

A 0.3 kepingan keluli mm usually refers to cold rolled stainless steel sheet in ultra-thin gauge form. It is widely used in precision manufacturing, elektronik, automotive interiors, peralatan rumah tangga, dan aplikasi hiasan. Pada ketebalan ini, 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.

Cold Rolling Process for 0.3 mm Lembaran Keluli Tahan Karat

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

Main Processing Steps

1. Penyediaan Gegelung Panas

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

2. Cold Rolling Reduction

Langkah	Penerangan
Multi-pass rolling	Thickness gradually reduced to 0.3 mm
High pressure rolling	Improves surface finish and density
Kawalan ketepatan	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. Pilihan Kemasan Permukaan

Jenis Selesai	Penerangan	Permohonan
2B Selesai	lancar, matte surface	Kegunaan industri
BA Selesai	Bright annealed surface	Aplikasi hiasan
Cermin Selesai	Permukaan yang sangat reflektif	Hiasan dalaman
Kemasan Berus	Linear texture surface	Panel perkakas

Key Processing Characteristics of 0.3 mm Lembaran Keluli Tahan Karat

Pada ketebalan ini, the material requires careful handling.

1. High Precision Cutting

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

2. Membengkok dan Membentuk

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
