Difference of stainless steel 304 and 204

Stainless steel is the abbreviation of stainless and acid resistant steel. The steel that is resistant to weak corrosion media such as air, steam, water or has stainless property is called stainless steel, while the steel that is resistant to chemical corrosion media (acid, alkali, salt and other chemical etching) is called acid resistant steel. Due to the difference in chemical composition, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid resistant steel is generally stainless.

1. Performance difference: Compared with 201 stainless steel, 304 stainless steel is softer, but 304 has better corrosion resistance, acid and alkali resistance.

2. Different application scope: 304 stainless steel has good corrosion resistance and high temperature resistance, which can be used in bathrooms, kitchens and humid coastal areas; The 201 stainless steel is mainly used in drying or decoration fields.

3. Difference of price: 304 stainless steel is more expensive than 201 stainless steel.
