- وصف
Thick stainless steel sheet refers to medium and heavy gauge stainless steel plates used in structural engineering, المعدات الصناعية, أوعية الضغط, بناء السفن, تصنيع الآلات, and heavy fabrication industries. Compared with thin stainless steel sheets, thick plates provide higher strength, قدرة تحمل أفضل, وتحسين الاستقرار الهيكلي.
The definition of “thick” stainless steel sheet varies by industry, but materials above approximately 3 mm thickness are generally classified as medium or thick stainless steel plates.
1. Common Thickness Range of Stainless Steel Sheets and Plates
| Category | نطاق السماكة | Typical Application |
|---|---|---|
| Thin Stainless Steel Sheet | 0.3 مم - 3 مم | Decoration, معدات المطبخ, precision fabrication |
| Medium Thickness Plate | 3 مم - 20 مم | التصنيع الهيكلي, الدبابات, الآلات |
| Thick Stainless Steel Plate | 20 مم - 60 مم | Heavy industry, أوعية الضغط |
| Extra Thick Stainless Steel Plate | 60 مم وما فوق | في الخارج, بناء السفن, heavy engineering |

3. مواصفات العرض والطول المشتركة
Thick stainless steel sheets are typically supplied in standard plate dimensions.
| عرض | الطول المشترك |
|---|---|
| 1000 مم | 2000 مم |
| 1219 مم | 2438 مم |
| 1500 مم | 3000 مم |
| 1800 مم | 6000 مم |
| 2000 مم | 6000 مم |
Custom cutting and processing sizes are also common in industrial applications.
4. Hot Rolled vs Cold Rolled Thickness Range
Cold Rolled Stainless Steel
- Usually produced from 0.3 مم ل 6 مم
- Better surface finish and dimensional accuracy
- Common surface finishes: 2ب, بكالوريوس, نحى
Hot Rolled Stainless Steel
- Commonly produced above 3 سمك مم
- Suitable for heavy plates and structural applications
- Typical surface finish: تشطيب رقم 1
Thicker stainless steel plates are generally manufactured using hot rolling processes.
5. Common Stainless Steel Grades for Thick Plates
| درجة | Main Characteristics |
|---|---|
| 304 | مقاومة التآكل العامة |
| 304ل | قابلية لحام أفضل |
| 316 | تحسين مقاومة الكلوريد |
| 316ل | منخفض الكربون, chemical applications |
| 310س | مقاومة درجات الحرارة العالية |
| 2205 دوبلكس | High strength and corrosion resistance |
6. Industrial Applications of Thick Stainless Steel Plates
Thick stainless steel sheets are widely used in:
- أوعية الضغط
- صهاريج تخزين المواد الكيميائية
- هياكل بناء السفن
- المنصات البحرية
- Heavy machinery manufacturing
- مبادلات حرارية
- Industrial pipelines
- Structural engineering systems
7. Processing Characteristics of Thick Stainless Steel
كلما زاد سمك, processing difficulty also increases.
Common processing methods:
- قطع البلازما
- القطع بنفث الماء
- التصنيع باستخدام الحاسب الآلي
- Heavy plate welding
- Rolling and forming
Key considerations:
- Higher welding heat input required
- Stronger forming equipment needed
- Slower machining speed
- Stress control during fabrication
