Let’s talk about a cold knowledge that everyone doesn’t know, stainless steel will also rust! We always think that stainless steel will not rust, but is it really so? Let us first understand the material of stainless steel.

The difference between stainless steel is that it is divided into 304 stainless steel and 201 stainless steel. The difference between 304 and 201 is their chemical composition. The difference between steel and iron is that the carbon content of steel is higher than that of iron, so the hardness of steel is higher than that of iron. Stainless steel is a kind of steel. The reason why stainless steel is stainless is that nickel, chromium, manganese and other metals are added on the basis of iron and carbon, so that it has anti-rust properties.

Generally, 304 stainless steel contains 8 nickels and 18 chromiums; while 201 stainless steels have a much lower nickel content, only about 0.8-1, and 13-15 chromiums. 304 has better corrosion resistance than 201, and the composition determines its physical and chemical properties.

When brown rust spots appear on the surface of stainless steel, people are surprised: "Stainless steel does not rust, and if it rusts, it is not stainless steel, and there may be a problem with the steel." In fact, this is a one-sided view of the lack of understanding of stainless steel.

Therefore, stainless steel will rust under certain conditions.

Not easy to rust principle:

Due to the influence of chromium, under the action of corrosive medium, a solid and dense oxide film is formed on the surface of steel parts, which is called "passivation film". This film isolates the metal from the external medium and prevents the metal from being further corroded; and it also has the ability to repair itself. If it is damaged, the chromium in the steel will interact with the The oxygen in the medium regenerates the passivation film and continues to play a protective role.

The rust of stainless steel is also related to the use environment. In different environments, stainless steels with different chromium content should be used. The level of chromium content is the fundamental factor that determines the performance of stainless steel, and the size of its corrosion resistance is changed with the chemical composition of the steel itself, the mutual state, the use conditions and the type of environmental media.
