Stainless Steel

Stainless Steel (Stainless Steel) is a high-alloy steel that is resistant to corrosion. It has a beautiful surface and does not need surface treatment such as color plating or paint. Therefore, many machinery factories often do not do any paint treatment in order to show that they are stainless steel. Black material (the so-called black material is the name of general steel) must be done. Anti-rust treatment.

Steel grades that are resistant to weak corrosive media such as air, steam, water, or stainless steel are called stainless steel; and steel grades that are resistant to chemical corrosion media (acid, alkali, salt, etc.) corrosion are called acid-resistant steel. In practical applications, the steel resistant to weak corrosion medium is often called stainless steel, and the steel resistant to chemical medium corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
