201 vs. 304 Stainless Steel Comparison
| Aspect | 201 Stainless Steel | 304 Stainless Steel |
|---|---|---|
| Nickel Content | Low (3.5-5.5%) | High (8-10.5%) |
| Corrosion Resistance | Good (indoor use) | Excellent (outdoor/chemical) |
| Magnetism | Magnetic | Non-magnetic |
| Cost | Lower | Higher |
| Best For | Decorative, indoor applications | High-performance, outdoor applications |
201 stainless steel is more budget-friendly but has lower nickel content (3.5-5.5%), making it less resistant to rust in wet or salty environments. It’s magnetic and ideal for indoor applications like decorative panels or furniture.
304 stainless steel contains more nickel (8-10.5%), giving it superior corrosion resistance for outdoor, kitchen, or industrial use. It’s non-magnetic and more durable but comes at a higher cost.
