Can rusty stainless steel still be called stainless steel?


As we know, stainless steel is a commonly used metal material, with corrosion resistance, wear resistance, high temperature resistance and other characteristics, so it is widely used in industrial, medical, construction and other fields. However, some people think that stainless steel will not rust, which is a wrong understanding.

In fact, stainless steel also rusts. The elements such as chromium and nickel in stainless steel can inhibit the oxidation reaction of iron ions to a certain extent, thereby reducing the rust rate of stainless steel. However, the iron ions in stainless steel will still oxidize under certain conditions, resulting in stainless steel rust.

The main reasons for stainless steel rust are as follows:

Water and oxygen in the air: the oxidation reaction of the surface of stainless steel requires the participation of water and oxygen, so if the surface of stainless steel is exposed to water and oxygen, it is easy to oxidize, resulting in stainless steel rust.

Corrosion of chemical substances: The oxidation reaction of stainless steel surface will also be affected by some chemical substances, such as acids, bases, salts and so on. These chemicals can react with oxides on the surface of stainless steel, causing stainless steel to rust.

The effect of temperature and humidity: the oxidation reaction of stainless steel is also related to temperature and humidity, and the higher the temperature and humidity, the faster the speed of stainless steel rust.

In order to prevent stainless steel from rusting, the following measures can be taken:

Keep the stainless steel surface dry: When using stainless steel products, keep the surface dry to avoid contact with moisture and oxygen.

Avoid chemical corrosion: When using stainless steel products, avoid exposure to acids, alkalis, salts and other chemicals, especially in high temperature and humid environments.

Control temperature and humidity: When using stainless steel products, it is necessary to control temperature and humidity to avoid the influence of too high or too low temperature and humidity on stainless steel.

Regular cleaning and maintenance: Regular cleaning and maintenance of stainless steel products can remove surface dirt and oxides and reduce the risk of rust.

In short, although stainless steel has the advantages of corrosion resistance, wear resistance and high temperature resistance, it will also rust. In order to prevent stainless steel from rusting, appropriate measures need to be taken to keep the stainless steel surface dry, avoid exposure to chemicals, control temperature and humidity, and regularly clean and maintain.

Tell everyone so much, you will think that the rusty stainless steel must be the material is not authentic? That's not true. The next time you encounter our stainless steel products are also rusty in life, you can not first suspect that you are buying fake stainless steel, of course, if it is really fake stainless steel material is 100% rust, really stainless steel products will also be likely to rust, but his corrosion resistance is better than other materials. Don't be misled by the name "stainless steel".
