SS 201 Harga Helaian
The reason why SS 201 sheet price is relatively cheap comes down to three key factors:
- Kandungan nikel yang lebih rendah (main cost driver)
- Use of manganese as a substitute alloying element
- Reduced corrosion resistance and narrower application range
- Penerangan
201 kepingan keluli tahan karat adalah keluli tahan karat austenit that is widely used as a cost-effective alternative to 304 keluli tahan karat. It maintains good mechanical properties but uses a different alloy composition to reduce cost.
kenapa 201 Stainless Steel Sheet Price Relatively Low?
The lower price of 201 stainless steel is mainly determined by its chemical composition and alloy design, rather than production quality.
1. Reduced Nickel Content (Core Reason)
Nickel is one of the most expensive elements in stainless steel.
| Gred | Nikel (Dalam) kandungan |
|---|---|
| 304 Keluli Tahan Karat | 8.0 – 10.5% |
| 201 Keluli Tahan Karat | 3.5 – 5.5% |
- 201 replaces part of the nickel with Mangan (Mn) dan nitrogen (N)
- This significantly reduces raw material cost
Kesimpulan:
Lower nickel = directly lower price
2. Higher Manganese Instead of Nickel
201 stainless steel contains higher manganese:
| unsur | 201 Keluli Tahan Karat |
|---|---|
| Mangan (Mn) | 5.5 – 7.5% |
- Manganese is much cheaper than nickel
- It helps maintain the austenitic structure
- Namun begitu, it reduces corrosion resistance compared to 304
3. Lower Corrosion Resistance
- 201 mempunyai less chromium-nickel synergy daripada 304
- More sensitive to:
- Humidity
- Acidic environments
- Coastal conditions
Kerana ini:
- It is mainly used in indoor or mild environments
- Lower performance = lower market price
4. Simpler Application Range
Berbanding dengan 304/316, 201 is typically used in:
- Panel hiasan
- Furniture and interior design
- Peralatan dapur (low-end)
- Door frames and handrails
It is not suitable for high-end industrial or marine use, which limits its value.
5. Market Supply and Demand
- 201 stainless steel is widely produced, especially in Asia
- Large production volume → high supply → competitive pricing
- Often used for price-sensitive projects
Mechanical Properties vs Cost Advantage
| Harta benda | 201 Keluli Tahan Karat | 304 Keluli Tahan Karat |
|---|---|---|
| kekuatan | Lebih tinggi (pengerasan kerja) | Sederhana |
| Rintangan Kakisan | Lebih rendah | Lebih tinggi |
| Kandungan Nikel | rendah | tinggi |
| Tahap Kos | rendah | Sederhana |
| Permohonan | Dalaman | Dalaman & luar |
Insight:
201 may have kekuatan yang lebih tinggi, tetapi ia corrosion resistance is weaker, which is why it is cheaper.
When is 201 Stainless Steel a Good Choice?
201 stainless steel sheet is ideal when:
- Budget is limited
- Application is indoor or dry environment
- Decorative appearance is required
- No strong corrosion resistance is needed
