What is the difference between 304 and 201 stainless steel

304 and 201 are the most common stainless steel materials, and they are different in composition, performance, and use environment.

1. Different ingredients

-304 stainless steel: contains 18% chromium and 8% nickel. This gives 304 stainless steel excellent corrosion resistance and toughness.

-201 stainless steel: contains about 17% chromium and about 4.5 nickel, manganese content is higher. Compared with 304, the corrosion resistance of 201 stainless steel is weakened.

2. Corrosion resistance

-304 stainless steel: Due to its high nickel content, 304 has excellent corrosion resistance and is stable in humid environments, acidic foods and chemicals.

-201 stainless steel: poor corrosion resistance, not suitable for long-term exposure to acid and alkali environment.

3. Hardness and toughness

-304 stainless steel: good toughness, suitable for making all kinds of kitchen utensils, tableware and medical equipment.

-201 stainless steel: high hardness, but toughness is not as good as 304, more used for decorative materials, some daily necessities.

4. Price

-304 stainless steel: due to high nickel content and complex process, the price is more expensive.

-201 stainless steel: low cost, the price is more people-friendly.
