Stainless Steel Bathroom Cabinet Incorporating Anti-Oxidation Steel

Stainless acid-resistant steel is referred to as stainless steel. It is composed of stainless steel and acid-resistant steel. In short, steel that resists atmospheric corrosion is called stainless steel, and steel that resists chemical corrosion is called acid-resistant steel. Stainless steel is a high-alloy steel in which more than 60% of iron is used as a matrix and alloying elements such as chromium, nickel, and molybdenum are added. Let's take a look at why Stainless Steel Bathroom Cabinet , stainless steel cabinets, stainless steel sinks, etc. are not easy to rust, what is the reason? When the chromium content in the steel exceeds 12%, the steel is not susceptible to corrosion and rust in air and dilute nitric acid. The reason is that chromium forms a very tight chromium oxide film on the steel surface, effectively protecting the steel from corrosion. The chromium content in stainless steel is generally more than 14%, but stainless steel does not absolutely rust. In coastal areas or where some air pollution is severe, when the chlorine content in the air is large, there may be some rust on the surface of the stainless steel exposed to the atmosphere, but these rust spots are limited to the surface and will not erode the internal matrix of the stainless steel. Generally speaking, steel with a Wcr greater than 12% has the characteristics of stainless steel. The microstructure of stainless steel can be divided into five categories according to the heat treatment: ferritic stainless steel, martensitic stainless steel, austenitic stainless steel. , austenitic-ferritic stainless steel and precipitated carbonized stainless steel.
