The difference between stainless steel 201, 304, 316



There are still many products used in stainless steel in our lives, such as stainless steel spoons, stainless steel basins, stainless steel pots, etc. If it is stainless steel used in industry, there are more stainless steel glass spigots, stainless steel spiders, stainless steel plates, stainless steel pipes, etc. It is really too much.

The difference between the most commonly used several stainless steel materials 201, 304, 316, these three materials are the most commonly used and most popular 304 stainless steel, because 304 stainless steel material is not only not easy to rust compared with 201, the price is also lower than 316 material, it can be said to be a cost-effective material.

There are three main reasons affecting the corrosion of stainless steel: the content of alloying elements, the smelting technology of production enterprises and low-carbon problems, of which most alloying elements depend on the amount of nickel and chromium, the normal chromium content in 10.5% steel is not easy to rust. The higher the content of chromium-nickel, the better the corrosion resistance, such as 304 material nickel content in 8-10%, chromium content reached 18-20%, such stainless steel in general circumstances will not rust. In fact, not rust is not always rust, but not easy to rust.

The 201 material is because of its less chromium and nickel content, so in the eyes of professionals 201 stainless steel is equivalent to the iron we know is very easy to rust. 316 stainless steel is an imported material, its corrosion resistance is better than 304, and it is generally used in some high-end equipment, such as aerospace, food, medical treatment, etc., of course, it will also be used in the sea, because the sea is salty. The air near the sea will also be filled with the salt of the sea, so the 316 material is generally used at the sea to ensure that it is not easy to rust.

The difference between 201, 304 and 316 stainless steel is very important, and consumers need to choose the right material according to their needs and budget when purchasing stainless steel products.
