3mm 스테인레스 시트
에이 3mm stainless sheet sits at the boundary between cold rolled and hot rolled production. The correct choice depends on:
- 표면 마감 요구 사항
- Dimensional tolerance
- 기계적 성질
- Application environment
General recommendation:
- 사용 cold rolled 3mm stainless sheet for precision and appearance
- 사용 hot rolled 3mm stainless plate for structural and heavy-duty use
- 설명
에이 3mm stainless sheet is a medium-thickness flat-rolled stainless steel product widely used in fabrication, 건설, 장비 제조, 산업 응용 분야.
이 두께에, stainless steel can be produced by both 냉간 압연 그리고 열간 압연, 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, 용인, 표면 마감, 및 기계적 특성.
냉간 압연 스테인레스 강판
Cold rolling is performed at room temperature after hot rolling, 이어서 어닐링 및 표면 마무리.
형질:
- 부드럽고 균일한 표면 (2비, BA finishes)
- High dimensional accuracy and tight tolerances
- Improved strength due to work hardening
- Excellent flatness
일반적인 두께 범위:
- 0.3mm – 6mm
- Most commonly used below 4.5mm
응용:
- 정밀 부품
- 장식 패널
- 주방 장비 및 가전 제품
- 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.
형질:
- 거친 표면 (1위 마무리, pickled or scaled)
- Lower dimensional accuracy compared to cold rolled
- Better ductility for forming and welding
- Suitable for heavy-duty applications
일반적인 두께 범위:
- 3mm – 200mm+
응용:
- 구조 제작
- 중장비
- 산업용 플랫폼
- Pressure vessels and tanks
Thickness and Process Comparison Table
| 프로세스 유형 | 두께 범위 | 용인 | 표면 마감 | 주요 응용 |
|---|---|---|---|---|
| Cold Rolled Stainless Sheet | 0.3mm – 6mm | 높은 정밀도 (±0.10mm) | 매끄러운 (2비, 학사) | 장식적인, 정밀 부품 |
| Hot Rolled Stainless Sheet | 3mm – 200mm+ | 낮은 정밀도 (±0.20–0.30mm) | 거친 (No.1) | 구조적, 산업의 |
Why 3mm is a Critical Thickness
그만큼 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. 치수 정확도
- 냉간 압연: tighter tolerances for precision manufacturing
- 열간압연: acceptable variation for structural use
4. Mechanical Behavior
- Cold rolled increases strength and hardness
- Hot rolled improves ductility and weldability
