Stainless steel is a type of steel that contains at least 10.5% chromium, which gives it its unique corrosion-resistant properties. In addition to chromium, stainless steel may also contain other alloying elements such as nickel, molybdenum, and titanium.
The corrosion resistance of stainless steel is due to the formation of a thin, invisible oxide layer on the surface of the material, known as the passive layer. This layer forms naturally in the presence of oxygen and provides a barrier against further oxidation or corrosion.
Stainless steel is commonly used in applications where corrosion resistance, durability, and hygiene are important factors. It is widely used in the manufacturing of kitchenware, medical equipment, chemical processing equipment, food processing equipment, and many other industrial applications.
