30ملم لوحة الفولاذ المقاوم للصدأ
30mm stainless steel plate is a heavy industrial stainless steel material commonly supplied in large widths and lengths for structural and engineering applications. Typical heavy plate thicknesses range from 20 mm to over 100 مم, مع 30 mm being a widely used specification for pressure vessels, offshore structures, and heavy equipment fabrication.
Common grades such as 304, 316, and duplex stainless steels are available in heavy plate form, providing excellent corrosion resistance, structural strength, and durability for demanding industrial environments.
- وصف
30mm stainless steel plate is a heavy thickness stainless steel material widely used in pressure vessels, بناء السفن, المعدات الكيميائية, offshore engineering, structural fabrication, and heavy industrial machinery. Compared with thin stainless steel sheets, 30mm plates provide much higher strength, rigidity, and load-bearing capacity.
Heavy stainless steel plates are typically produced through hot rolling processes and are available in various grades, الاعراض, أطوال, and custom dimensions depending on industrial requirements.
1. What Is Considered a Thick Stainless Steel Plate?
Stainless steel flat products are generally classified by thickness:
| Category | نطاق السماكة |
|---|---|
| Thin Sheet | 0.3 مم - 3 مم |
| Medium Plate | 3 مم - 20 مم |
| لوحة سميكة | 20 مم - 60 مم |
| لوحة سميكة اضافية | 60 مم وما فوق |
A 30mm stainless steel plate belongs to the heavy plate category.
2. Common Thickness Specifications for Heavy Stainless Steel Plates
Heavy stainless steel plates are commonly available in the following thicknesses:
| Common Thickness |
|---|
| 20 مم |
| 25 مم |
| 30 مم |
| 40 مم |
| 50 مم |
| 60 مم |
| 80 مم |
| 100 مم |
| 120 مم وما فوق |
The thicker the plate, the more it is used for structural and heavy industrial applications.
3. مواصفات العرض والطول المشتركة
30mm stainless steel plates are commonly supplied in large industrial dimensions.
| عرض | طول |
|---|---|
| 1500 مم | 3000 مم |
| 1800 مم | 6000 مم |
| 2000 مم | 6000 مم |
| 2500 مم | 6000 مم |
| 3000 مم | 8000 مم |
Custom cutting and processing sizes are widely available for engineering projects.
4. Common Stainless Steel Grades for 30mm Plates

|---|---|
| 304 | مقاومة التآكل العامة |
| 304ل | Improved weldability |
| 316 | مقاومة أفضل للكلوريد |
| 316ل | Chemical and marine applications |
| 310س | مقاومة درجات الحرارة العالية |
دوبلكس ستانلس ستيل
| درجة | صفات |
|---|---|
| 2205 | High strength and corrosion resistance |
| 2507 | سوبر دوبلكس, extreme corrosion resistance |
Ferritic and Martensitic Grades
Used for specific structural or heat-resistant applications.
5. Hot Rolled Production of Thick Stainless Steel Plates
Heavy stainless steel plates such as 30mm are mainly produced using hot rolling.
Characteristics of Hot Rolled Plates
- Suitable for large thicknesses
- استقرار هيكلي داخلي أفضل
- Higher production efficiency for heavy plates
- Usually supplied with No.1 surface finish
Compared with cold rolled products:
- Surface is rougher
- Thickness tolerance is larger
- More suitable for heavy engineering applications
6. Processing Methods for 30mm Stainless Steel Plate
Because of the heavy thickness, specialized fabrication methods are required.
Common processing methods:
- قطع البلازما
- القطع بنفث الماء
- CNC flame cutting
- اللحام الثقيل
- Rolling and forming
- Machining and milling
Processing considerations:
- High welding heat input required
- Preheating may be needed for some grades
- Strong forming equipment required
- Stress control during fabrication is important
7. Applications of 30mm Stainless Steel Plates
30mm stainless steel plates are widely used in:
- أوعية الضغط
- صهاريج تخزين المواد الكيميائية
- Offshore engineering
- هياكل بناء السفن
- Industrial reactors
- مبادلات حرارية
- Heavy machinery manufacturing
- Structural support systems
8. Advantages of Heavy Stainless Steel Plates
- قوة هيكلية عالية
- مقاومة ممتازة للتآكل
- عمر خدمة طويل
- أداء جيد في درجات الحرارة العالية
- Strong load-bearing capability
- Suitable for harsh industrial environments
