SS 316 Giá tấm
The pricing of stainless steel sheets is directly linked to alloy composition and performance level. In the 201–304–316–430 range, 316 stainless steel sheet represents the premium grade, mainly used in demanding environments where corrosion resistance is critical, while lower grades are selected for cost-sensitive and indoor applications.
- Sự miêu tả
The price of stainless steel sheet is mainly determined by:
- Thành phần hợp kim (niken, crom, hàm lượng molypden)
- Corrosion resistance level
- Mechanical performance
- Khó xử lý
Among common grades, 201, 304, 316, Và 430 tấm thép không gỉ show clear differences in both cost level and performance.
Performance Comparison of Stainless Steel Sheet Grades
| Cấp | Kiểu | Chống ăn mòn | Sức mạnh | Khả năng định dạng | Ứng dụng điển hình |
|---|---|---|---|---|---|
| 201 | Austenit (low nickel) | Thấp–Trung bình | Trung bình | Tốt | Trang trí nội thất, low-cost fabrication |
| 304 | Austenit | Tốt | Trung bình | Xuất sắc | Thiết bị thực phẩm, general industrial use |
| 316 | Austenit (Mo added) | Xuất sắc | Trung bình | Tốt | Hàng hải, hóa chất, coastal environments |
| 430 | Ferit | Trung bình | Thấp hơn | Vừa phải | Thiết bị gia dụng, tấm trang trí |
Price Ranking (From Low to High)
The general stainless steel sheet price order is:
430 < 201 < 304 < 316
Reason Behind Price Differences
1. Nội dung niken
- 201: Very low nickel (cost-saving substitution with manganese)
- 304: ~8% nickel
- 316: ~10% nickel + molypden (chi phí cao hơn)
- 430: No nickel (ferritic grade, lower cost but also lower performance)
2. Corrosion Resistance Requirement
- 316 requires molybdenum for strong chloride resistance → higher cost
- 304 balances cost and performance
- 201 reduces cost by lowering nickel content
- 430 avoids nickel entirely but sacrifices corrosion resistance
3. Application Level
- Công nghiệp & marine → 316 (highest cost level)
- General fabrication → 304
- Budget decoration → 201 / 430
316 Stainless Steel Sheet Price Position
316 stainless steel sheet is the highest-priced among common stainless steel sheet grades because it includes:
- Higher nickel content
- Added molybdenum (Mo) for pitting corrosion resistance
- Superior performance in seawater and chemical environments
Tại sao 316 Costs More:
- Better resistance to chloride corrosion
- Longer service life in harsh environments
- More stable performance under chemical exposure
- Higher raw material alloy cost
Typical Application-Based Price Positioning
| Application Requirement | Recommended Grade | Mức chi phí |
|---|---|---|
| Marine environment | 316 | Cao |
| Công nghiệp hóa chất | 316 / 304 | High–Medium |
| Thiết bị thực phẩm | 304 | Trung bình |
| Indoor decoration | 201 / 430 | Thấp |
| Thiết bị gia dụng | 430 | Thấp |
Key Takeaways
- 316 tấm thép không gỉ is the most expensive among common grades due to its superior corrosion resistance and molybdenum content
- 304 tấm thép không gỉ is the most widely used balance of cost and performance
- 201 tấm thép không gỉ is a cost-effective alternative with reduced corrosion resistance
- 430 tấm thép không gỉ is the lowest-cost option but with limited corrosion resistance
