Cold Rolling Process for 0.3 mmステンレス鋼板

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

Main Processing Steps

1. Hot Rolled Coil Preparation

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

2. Cold Rolling Reduction

ステップ	説明
Multi-pass rolling	Thickness gradually reduced to 0.3 mm
High pressure rolling	Improves surface finish and density
精密制御	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. 酸洗と表面洗浄

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

5. 表面仕上げオプション

仕上げタイプ	説明	応用
2B仕上げ	スムーズ, マットな表面	産業用
BA仕上げ	Bright annealed surface	装飾用途
鏡面仕上げ	高反射表面	室内装飾
つや消し仕上げ	Linear texture surface	アプライアンスパネル

Key Processing Characteristics of 0.3 mmステンレス鋼板

この厚みで, the material requires careful handling.

1. High Precision Cutting

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

2. 曲げ加工

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
