30mm Pelat Baja Tahan Karat
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 sampai selesai 100 mm, dengan 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.
- Keterangan
30mm stainless steel plate is a heavy thickness stainless steel material widely used in pressure vessels, pembuatan kapal, peralatan kimia, offshore engineering, structural fabrication, and heavy industrial machinery. Compared with thin stainless steel sheets, 30mm plates provide much higher strength, kekakuan, and load-bearing capacity.
Heavy stainless steel plates are typically produced through hot rolling processes and are available in various grades, lebar, panjang, 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:
| Kategori | Kisaran Ketebalan |
|---|---|
| Thin Sheet | 0.3 mm – 3 mm |
| Medium Plate | 3 mm – 20 mm |
| Pelat Tebal | 20 mm – 60 mm |
| Pelat Ekstra Tebal | 60 mm ke atas |
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 mm |
| 25 mm |
| 30 mm |
| 40 mm |
| 50 mm |
| 60 mm |
| 80 mm |
| 100 mm |
| 120 mm ke atas |
The thicker the plate, the more it is used for structural and heavy industrial applications.
3. Spesifikasi Lebar dan Panjang Umum
30mm stainless steel plates are commonly supplied in large industrial dimensions.
| Lebar | Panjang |
|---|---|
| 1500 mm | 3000 mm |
| 1800 mm | 6000 mm |
| 2000 mm | 6000 mm |
| 2500 mm | 6000 mm |
| 3000 mm | 8000 mm |
Custom cutting and processing sizes are widely available for engineering projects.
4. Common Stainless Steel Grades for 30mm Plates
Baja Tahan Karat Austenitik
| Nilai | Karakteristik Utama |
|---|---|
| 304 | Ketahanan korosi secara umum |
| 304L | Improved weldability |
| 316 | Ketahanan klorida yang lebih baik |
| 316L | Aplikasi kimia dan kelautan |
| 310S | Ketahanan suhu tinggi |
Baja Tahan Karat Dupleks
| Nilai | Karakteristik |
|---|---|
| 2205 | Kekuatan tinggi dan ketahanan terhadap korosi |
| 2507 | Super dupleks, 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
- Stabilitas struktural internal yang lebih baik
- 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:
- Pemotongan plasma
- Pemotongan jet air
- CNC flame cutting
- Pengelasan berat
- 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:
- Bejana tekan
- Tangki penyimpanan bahan kimia
- Offshore engineering
- Struktur pembuatan kapal
- Industrial reactors
- Penukar panas
- Heavy machinery manufacturing
- Structural support systems
8. Advantages of Heavy Stainless Steel Plates
- Kekuatan struktural yang tinggi
- Ketahanan korosi yang sangat baik
- Umur panjang
- Performa suhu tinggi yang bagus
- Strong load-bearing capability
- Suitable for harsh industrial environments
