201 vs 304 stainless steel: what’s the difference?

What is the difference between 304 stainless steel and 201 stainless steel, which are common in daily life? How to easily identify these two materials and which stainless steel material to choose?

201 stainless steel vs 304 Chemical composition
- 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, and has a higher manganese content. Compared with 304, the corrosion resistance of 201 stainless steel is weakened.

201 stainless steel vs 304 Corrosion resistance
- 304 stainless steel: Due to the high nickel content, 304 has excellent corrosion resistance and can remain stable in humid environments, acidic foods and chemicals.
- 201 stainless steel: poor corrosion resistance, not suitable for long-term contact with acid and alkali environments.

201 stainless steel vs 304 Hardness and toughness
- 304 stainless steel: good toughness, suitable for making various kitchen utensils, tableware and medical equipment, etc.
- 201 stainless steel: higher hardness, but not as tough as 304, mostly used for decorative materials and some daily necessities.

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

201 stainless steel vs 304 application
201 has the advantages of acid and alkali resistance, high density, and polishing without bubbles, and is suitable for decorative pipes, industrial pipes and other products. 304 stainless steel has good processing performance and high toughness, and is suitable for industrial and furniture industries.
