3mmステンレスシート
あ 3mm stainless sheet sits at the boundary between cold rolled and hot rolled production. The correct choice depends on:
- Surface finish requirements
- 寸法許容差
- 機械的性質
- アプリケーション環境
General recommendation:
- 使用 cold rolled 3mm stainless sheet for precision and appearance
- 使用 hot rolled 3mm stainless plate for structural and heavy-duty use
- 説明
あ 3mm stainless sheet is a medium-thickness flat-rolled stainless steel product widely used in fabrication, 工事, 装置製造, および産業用途.
この厚みで, stainless steel can be produced by both 冷間圧延 そして 熱間圧延, making it an important selection point in engineering and procurement.
Cold Rolled vs Hot Rolled Stainless Steel
The rolling process determines the sheet’s thickness capability, 許容範囲, 表面仕上げ, および機械的特性.
冷間圧延ステンレス鋼板
Cold rolling is performed at room temperature after hot rolling, followed by annealing and surface finishing.
特徴:
- 滑らかで均一な表面 (2B, BA finishes)
- High dimensional accuracy and tight tolerances
- Improved strength due to work hardening
- Excellent flatness
Typical thickness range:
- 0.3mm – 6mm
- Most commonly used below 4.5mm
アプリケーション:
- 精密部品
- 化粧パネル
- Kitchen equipment and appliances
- Medical and food-grade equipment
Hot Rolled Stainless Steel Sheet
Hot rolling is carried out at high temperatures above recrystallization, allowing larger deformation and thicker products.
特徴:
- Rough surface (No.1 finish, pickled or scaled)
- Lower dimensional accuracy compared to cold rolled
- Better ductility for forming and welding
- Suitable for heavy-duty applications
Typical thickness range:
- 3mm – 200mm+
アプリケーション:
- 構造製作
- Heavy machinery
- 産業用プラットフォーム
- Pressure vessels and tanks
Thickness and Process Comparison Table
| プロセスの種類 | 厚さの範囲 | 許容範囲 | 表面仕上げ | 主な用途 |
|---|---|---|---|---|
| Cold Rolled Stainless Sheet | 0.3mm – 6mm | 高精度 (±0.10mm) | スムーズ (2B, BA) | 装飾的な, 精密部品 |
| Hot Rolled Stainless Sheet | 3mm – 200mm+ | 精度が低い (±0.20–0.30mm) | 粗い (No.1) | Structural, 工業用 |
Why 3mm is a Critical Thickness
の 3mm thickness is considered a transition point between cold rolled and hot rolled stainless steel.
Key Reasons:
1. Equipment and Rolling Capability
- Cold rolling requires higher pressure as thickness increases
- Efficient production typically limits cold rolled sheets to ≤6mm
- Hot rolling can easily produce thicker sections from slabs
2. Surface Requirements
- Cold rolled sheets are selected when appearance and smoothness are important
- Hot rolled sheets are used where surface finish is not critical
3. 寸法精度
- 冷間圧延: tighter tolerances for precision manufacturing
- 熱間圧延: acceptable variation for structural use
4. 機械的動作
- Cold rolled increases strength and hardness
- Hot rolled improves ductility and weldability
Standard Sizes for 3mm Stainless Sheet
Common Sheet Formats
| 厚さ | 幅 (mm) | 長さ (mm) | Supply Form |
|---|---|---|---|
| 3.0 mm | 1000 / 1219 / 1500 | 2000 / 2438 / 3000 | シート |
