Stainless steel is the abbreviation of stainless and acid-resistant steel. The steel that is resistant to weak corrosive media such as air, steam, and water or has stainless is called stainless steel; and the steel that is resistant to chemical corrosion is called acid-resistant steel.

Due to the difference in chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless. The term "stainless steel" does not simply refer to one type of stainless steel, but to more than one hundred industrial stainless steels, each developed to perform well in its specific field of application. There are usually only six steel grades associated with building construction applications. They all contain 17-22% chromium, and the better grades also contain nickel. The addition of molybdenum can further improve atmospheric corrosion, especially corrosion resistance to chloride-containing atmospheres.

Stainless steel is often divided into: martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic stainless steel and precipitation hardening stainless steel according to the structure state. In addition, it can be divided into: chromium stainless steel, chromium-nickel stainless steel and chromium-manganese-nitrogen stainless steel according to the composition.

The main properties of stainless steel are weldability, corrosion resistance, polishability and heat resistance. Therefore, stainless steel products are widely used in various scenarios.

There are many reasons why surface finishing of stainless steel is important in architectural applications. Corrosive environments require smooth surfaces because smooth surfaces are less prone to fouling. Dirt deposits can rust or even cause corrosion in stainless steel.

In addition, stainless steel is also the most commonly used material for elevator decorative panels. Although the fingerprints on the surface can be wiped off, it will affect the appearance. Therefore, it is best to choose a suitable surface to prevent fingerprints.

Stainless steel surfaces are often scribbled in public places, however, one of its important properties is that they can be washed off, a distinguishing feature of stainless steel over aluminum.

Stainless steel is best used in hospitals or other areas where hygiene is critical, such as: food processing, catering, brewing and chemical industry, not only because it is easy to clean every day, sometimes with chemical cleaning agents, but also because it is less prone to bacteria growth .
