30mmステンレス鋼板
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～以上 100 mm, と 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.
- 説明
30mm stainless steel plate is a heavy thickness stainless steel material widely used in pressure vessels, 造船, 化学装置, offshore engineering, structural fabrication, and heavy industrial machinery. Compared with thin stainless steel sheets, 30mm plates provide much higher strength, 剛性, and load-bearing capacity.
Heavy stainless steel plates are typically produced through hot rolling processes and are available in various grades, 幅, 長さ, 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 | 厚さの範囲 |
|---|---|
| Thin Sheet | 0.3 mm – 3 mm |
| Medium Plate | 3 mm – 20 mm |
| 厚板 | 20 mm – 60 mm |
| 極厚板 | 60 mm以上 |
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以上 |
The thicker the plate, the more it is used for structural and heavy industrial applications.
3. 共通の幅と長さの仕様
30mm stainless steel plates are commonly supplied in large industrial dimensions.
| 幅 | 長さ |
|---|---|
| 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

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
- 内部構造の安定性が向上
- 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:
- プラズマ切断
- ウォータージェット切断
- CNC flame cutting
- 重溶接
- 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:
- 圧力容器
- 化学薬品貯蔵タンク
- Offshore engineering
- Shipbuilding structures
- Industrial reactors
- 熱交換器
- Heavy machinery manufacturing
- Structural support systems
8. Advantages of Heavy Stainless Steel Plates
- 高い構造強度
- 優れた耐食性
- 長寿命
