Introduction of SUS304 stainless steel and comparison between 201 material and 304 material

Now SUS304 stainless steel is more and more widely used in the market. At the same time, there are many manufacturers who use 201 material to replace 304 material. After one to two years of use, they have brought huge economic losses to customers. Here to popularize some knowledge about SUS304 stainless steel material. According to the above table, we know the chemical composition of stainless steel. The reason why stainless steel is called "stainless" is because it contains Ni. What does Ni mean? Let's focus on it: Nickel (Ni): approximately silvery white, hard and ductile A ferromagnetic metal element that is highly polished and corrosion-resistant. It is green when dissolved in nitric acid. It is mainly used in alloys (such as nickel steel and nickel silver) and as catalysts (such as Raney nickel, especially as a catalyst for hydrogenation) [nickel].

Element use: Metal elements with ferromagnetism, which can be highly polished and corrosion-resistant, mainly used in alloys (such as nickel steel and nickel silver) and as catalysts (such as Raney nickel, especially for hydrogenation catalysts) , can be used to make currency, etc., and can be plated on other metals to prevent rust. Based on the above knowledge, we can easily understand that stainless steel does not rust because it contains nickel, so it does not rust and is corrosion-resistant. However, the 201 material on the market does not contain nickel at all, so it cannot meet the standard of drinking water, and Because it is not corrosion-resistant and easy to rust, it has a short service life, is easily damaged, and is difficult to maintain. The glossiness of SUS304 stainless steel is much better than that of 201 material. When customers choose materials, they can distinguish them through liquid medicine detection or comparison of glossiness. I hope this article can bring you a little understanding of the materials of stainless steel water tanks.
