- Descripción
Thick stainless steel sheet refers to medium and heavy gauge stainless steel plates used in structural engineering, equipos industriales, recipientes a presión, construcción naval, fabricación de maquinaria, and heavy fabrication industries. Compared with thin stainless steel sheets, thick plates provide higher strength, better load-bearing capacity, and improved structural stability.
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
| Categoría | Rango de espesor | Aplicación típica |
|---|---|---|
| Thin Stainless Steel Sheet | 0.3 milímetros – 3 milímetros | Decoración, equipo de cocina, fabricación de precisión |
| Medium Thickness Plate | 3 milímetros – 20 milímetros | fabricación estructural, tanques, maquinaria |
| Thick Stainless Steel Plate | 20 milímetros – 60 milímetros | Heavy industry, recipientes a presión |
| Extra Thick Stainless Steel Plate | 60 mm y más | Costa afuera, construcción naval, heavy engineering |
2. Common Standard Thickness Specifications

3. Especificaciones comunes de ancho y largo
Thick stainless steel sheets are typically supplied in standard plate dimensions.
| Ancho | Longitud común |
|---|---|
| 1000 milímetros | 2000 milímetros |
| 1219 milímetros | 2438 milímetros |
| 1500 milímetros | 3000 milímetros |
| 1800 milímetros | 6000 milímetros |
| 2000 milímetros | 6000 milímetros |
Custom cutting and processing sizes are also common in industrial applications.
4. Hot Rolled vs Cold Rolled Thickness Range
Acero inoxidable laminado en frío
- Usually produced from 0.3 mm a 6 milímetros
- Better surface finish and dimensional accuracy
- Common surface finishes: 2B, licenciado en Letras, cepillado
Acero inoxidable laminado en caliente
- Commonly produced above 3 MM GRISIÓN
- Suitable for heavy plates and structural applications
- Typical surface finish: Acabado número 1
Thicker stainless steel plates are generally manufactured using hot rolling processes.
5. Common Stainless Steel Grades for Thick Plates
| Calificación | Características principales |
|---|---|
| 304 | Resistencia general a la corrosión |
| 304l | Better weldability |
| 316 | Improved chloride resistance |
| 316l | Bajo en carbono, chemical applications |
| 310S | Resistencia a altas temperaturas |
| 2205 Dúplex | Alta resistencia y resistencia a la corrosión. |
6. Industrial Applications of Thick Stainless Steel Plates
Thick stainless steel sheets are widely used in:
- Recipientes a presión
- Tanques de almacenamiento de químicos
- Shipbuilding structures
- Plataformas marinas
- Heavy machinery manufacturing
- Intercambiadores de calor
- Tuberías industriales
- Structural engineering systems
7. Processing Characteristics of Thick Stainless Steel
A medida que aumenta el grosor, processing difficulty also increases.
Métodos de procesamiento comunes:
- Corte de plasma
- Corte de chorro de agua
- Mecanizado CNC
- Heavy plate welding
- Rolling and forming
Consideraciones clave:
- Higher welding heat input required
- Stronger forming equipment needed
- Slower machining speed
- Stress control during fabrication
