20g Tấm thép không gỉ
20G stainless steel sheet corresponds to a thickness of approximately 0.81 mm, making it a widely used thin-gauge stainless steel material. It is commonly supplied in standard sheet sizes such as 4×8 ft and 4×10 ft, and is available in grades like 304, 316, 430, Và 201.
- Sự miêu tả
MỘT 20G stainless steel sheet refers to stainless steel sheet material identified by the máy đo (G) system, where “20G” indicates a specific thickness level. It is commonly used in HVAC systems, thiết bị nhà bếp, chế tạo ánh sáng, linh kiện ô tô, và vỏ công nghiệp.
In modern engineering, stainless steel sheet thickness is usually specified in millimeters (mm), while the gauge system is still widely used in North America and some industrial fields.
làm gì 20 Máy đo (20G) Mean?
In the gauge system:
- MỘT higher gauge number = thinner sheet
- MỘT lower gauge number = thicker sheet
20G Stainless Steel Thickness Conversion
| Máy đo | độ dày (mm) | độ dày (inch) |
|---|---|---|
| 20G | 0.81 mm | 0.032 TRONG |
👉 20G stainless steel sheet is considered a thin sheet, suitable for light structural and fabrication work.
Common Stainless Steel Sheet Thickness Range
Stainless steel sheets are available in a wide thickness range depending on application requirements.
| Category | Phạm vi độ dày | Sử dụng điển hình |
|---|---|---|
| Tấm siêu mỏng | 0.1 – 0.5 mm | Electronics, trang trí |
| Tấm mỏng | 0.5 – 1.5 mm | HVAC, appliance panels |
| Tấm vừa | 1.5 – 6 mm | Chế tạo công nghiệp |
| Thick plate | 6 mm trở lên | Structural and heavy-duty use |
20G (0.81 mm) belongs to the thin sheet category.
Common Stainless Steel Sheet Sizes
20G stainless steel sheets are typically supplied in standard industrial sizes.
| Size Type | Kích thước |

Common Stainless Steel Grades for 20G Sheet
| Cấp | Đặc trưng | Ứng dụng |
|—|—|
| 304 | Khả năng chống ăn mòn tuyệt vời, sử dụng chung | Công nghiệp & trang trí |
| 316 | Khả năng chống ăn mòn cao (lớp biển) | Hóa chất & marine environments |
| 430 | Thép không gỉ ferritic từ tính | Tấm thiết bị |
| 201 | Cost-effective stainless steel | Trang trí nội thất |
Gauge vs Metric Thickness System
Gauge System (G)
- Common in North America
- Based on historical metal thickness standards
- Not linear (difference between gauges varies)
Metric System (mm)
- International standard
- More accurate and widely used in engineering
