3. What Are Stainless Steel Sheets?
Stainless steel sheets are flat-rolled metal products available in various:
- Thicknesses (gauge/mm)
- Surface finishes (2B, BA, No.4, HL)
- Grades (201, 304, 316, etc.)
They are widely used in:
- Construction
- Food processing
- Chemical industries
- Appliances and decoration
4. Chemical Composition Comparison
| Element | 201 | 304 | 316 |
|---|---|---|---|
| Chromium | 16–18% | 18–20% | 16–18% |
| Nickel | 3.5–5.5% | 8–10.5% | 10–14% |
| Molybdenum | ❌ | ❌ | 2–3% |
Key Insight:
- Nickel improves corrosion resistance
- Molybdenum (316) adds chloride resistance
5. 304 vs 316 vs 201: Core Differences
| Property | 201 | 304 | 316 |
|---|---|---|---|
| Corrosion Resistance | Moderate | High | Very High |
| Cost | Low | Medium | High |
| Durability | Moderate | High | Very High |
| Application Range | Limited | Wide | Premium |
| Outdoor Use | ❌ | ✔ | ✔✔ |
6. Corrosion Resistance (Most Important Factor)
