30placa de aço inoxidável mm
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 milímetros, com 30 mm being a widely used specification for pressure vessels, offshore structures, and heavy equipment fabrication.
Notas comuns como 304, 316, and duplex stainless steels are available in heavy plate form, providing excellent corrosion resistance, structural strength, and durability for demanding industrial environments.
- Descrição
30mm stainless steel plate is a heavy thickness stainless steel material widely used in pressure vessels, construção naval, equipamento químico, offshore engineering, structural fabrication, and heavy industrial machinery. Comparado com chapas finas de aço inoxidável, 30mm plates provide much higher strength, rigidez, and load-bearing capacity.
Heavy stainless steel plates are typically produced through hot rolling processes and are available in various grades, larguras, comprimentos, 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 | Faixa de espessura |
|---|---|
| Thin Sheet | 0.3 milímetros – 3 milímetros |
| Prato Médio | 3 milímetros – 20 milímetros |
| Prato Grosso | 20 milímetros – 60 milímetros |
| Prato Extra Grosso | 60 mm e acima |
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 milímetros |
| 25 milímetros |
| 30 milímetros |
| 40 milímetros |
| 50 milímetros |
| 60 milímetros |
| 80 milímetros |
| 100 milímetros |
| 120 mm e acima |
The thicker the plate, the more it is used for structural and heavy industrial applications.
3. Especificações comuns de largura e comprimento
30mm stainless steel plates are commonly supplied in large industrial dimensions.
| Largura | Comprimento |
|---|---|
| 1500 milímetros | 3000 milímetros |
| 1800 milímetros | 6000 milímetros |
| 2000 milímetros | 6000 milímetros |
| 2500 milímetros | 6000 milímetros |
| 3000 milímetros | 8000 milímetros |
Custom cutting and processing sizes are widely available for engineering projects.
4. Common Stainless Steel Grades for 30mm Plates
Aço Inoxidável Austenítico
| Nota | Principais características |
|---|---|
| 304 | Resistência geral à corrosão |
| 304eu | Improved weldability |
| 316 | Better chloride resistance |
| 316eu | Aplicações químicas e marítimas |
| 310S | Resistência a altas temperaturas |
Aço Inoxidável Duplex
| Nota | Características |
|---|---|
| 2205 | Alta resistência e resistência à corrosão |
| 2507 | Superduplex, 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
- Better internal structural stability
- 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.
Métodos de processamento comuns:
- Corte a plasma
- Corte por jato de água
- CNC flame cutting
- Heavy welding
- Rolando e formando
- 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:
- Vasos de pressão
- Tanques de armazenamento de produtos químicos
- Offshore engineering
- Estruturas de construção naval
- Industrial reactors
- Trocadores de calor
- Fabricação de máquinas pesadas
- Structural support systems
8. Advantages of Heavy Stainless Steel Plates
- Alta resistência estrutural
- Excelente resistência à corrosão
- Longa vida útil
- Good high-temperature performance
- Strong load-bearing capability
- Suitable for harsh industrial environments
