The Mystery of 1.4404 Stainless Steel Plate Does Not Rust

May. 24, 2019

1.4404 Stainless Steel Plate does not rust the "mystery" Michael L. Free, a metallurgical engineer at the University of Utah, provides an explanation for the "mystery" of stainless steel without rust: stainless steel maintains stainless steel, or does not rust due to the alloying elements of stainless steel and The reactions and reactions that occur between environments. Stainless steel contains iron, chromium, manganese, silicon, carbon, and in many cases, a large amount of nickel and molybdenum. These elements react with oxygen from water and air to form a very thin and stable film composed of corrosion products such as metal chlorides and hydroxides. Aluminum plays a leading role in the reaction with oxygen to form such a corrosion product film. In fact, all stainless steels account for 10% of the aluminum content by definition.

The presence of such a stabilizing film as a barrier limits the oxygen and water to the underlying metal surface, avoiding further corrosion. Because the formation of such a film is so easy and fast, even with only a small amount of atomic film, the degree of corrosion is reduced to a very low level. The fact that the film is much thinner than the wavelength of light makes it visible to the naked eye only with the help of modern tools. Therefore, although steel is corrosive at the atomic level, 310s Stainless Steel Sheet exhibits stainless characteristics. The generally cheap steel, on the other hand, reacts with oxygen from the water to form a relatively unstable iron oxide/hydroxide film that continues to grow over time and continues to be exposed to water and air. in. In this way, this type of film, also known as rust, quickly reaches a sufficiently thick level when exposed to water and air, making it extremely visible to the naked eye.
