What is the difference between 201 stainless steel and 304 stainless steel?

The difference between 201 stainless steel and 304 is not obvious, but its chemical composition, mechanical performance, corrosion resistance, and the scope of use are essentially different. The specifics are as follows:

201 stainless steel

1.201 and 304 stainless steel contained in various elements are different:

304 stainless steel's chromium and nickel content far exceeds 201 stainless steel. The nickel content in 201 is greater than equal to 1.0%, while the 304 nickel content is greater than equal to 8.0%; the chromium content is greater than equal to 13.0%; and the 304 chromium content is greater than equal to 18.0%.

201 stainless steel

2.201 and 304 stainless steel's mechanical properties are different:

201 stainless steel carbon content and manganese content are much higher than 304, so 201 stainless steel hardness is higher than 304, and rigidity is crispy. 304 has a good stretching performance.

304 stainless steel

3.201 and 304 stainless steel corrosion resistance is different:

304 stainless steel, also known as 18-8 stainless steel, good corrosion resistance should be widely daily. 201 stainless steel has a high manganese content and low nickel chromium content. 

304 stainless steel

4.The price of 201 and 304 stainless steel is different:

Because the two most expensive elements in stainless steel ingredients are chromium and nickel. The content of 2 elements in stainless steel is low. Generally, the price of stainless steel is only about 60%of the price of 304.

304 stainless steel

5.201 and 304 stainless steel waste recycling prices are different:

304 stainless steel waste recycling value is generally 70-75%of the original value. Although the unit price of 201 stainless steel is low, its waste recycling is generally 45-50%of the original value.
