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

1. Different ingredients

The primary reason for the difference is that the composition of 201 stainless steel and 304 stainless steel is not the same. Although both belong to chromium nickel alloy, but the specific proportion of composition is different, the chromium content of 201 stainless steel is about 15%, and 304 stainless steel contains 18%; Similarly, 201 stainless steel contains 5% nickel, while 304 stainless steel contains more nickel, about 9%. So this also causes from the appearance of the two color is different, 201 stainless steel surface is more bright, and 304 stainless steel surface is a matte effect.

2. Different performance

As we all know, 304 stainless steel has good corrosion resistance and is not easy to rust, but compared with 304 stainless steel, the material will be softer. 201 stainless steel hardness will be greater, but in terms of corrosion resistance will not be as good as 304 stainless steel, although the surface is more bright, but in the process of use is more prone to rust.

3. Different uses

It is because of the different composition and performance of the two, resulting in specific uses are also different. 201 stainless steel corrosion resistance is not high quality, but higher density, no internal pinhole, so it is generally suitable for dry environment, such as the field of decoration, industrial products and so on, can well meet the needs. 304 stainless steel has better corrosion resistance, so it can be used in industry, home improvement, medical and other industries, at the same time, like some coastal or relatively wet areas are also very suitable.

4. Different prices

Finally, the two are also slightly different in price, usually under conditions, the price of 304 stainless steel is higher than that of 201 stainless steel.

201 stainless steel and 304 stainless steel as common stainless steel, also have their own more prominent characteristics, understand their differences, we can better according to the actual needs to choose!
