Stainless steel is a metal alloy that is both corrosion-resistant and tough. It can resist corrosion while maintaining excellent strength and easy cutting properties. They are widely used in the industrial, aviation, marine and construction industries, and are also used to manufacture automotive parts, medical devices, and general supplies. The main components of stainless steel are alloys of chromium, manganese and cobalt, as well as some trace elements.
Chromium is one of the main components of stainless steel and a key component of stainless steel. It can prevent metal corrosion. Usually, the chromium content is 10%~30%. The main function of chromium is to form a protective film to resist oxides in the air and inhibit metal corrosion.
Manganese is another main component in stainless steel. Its content is about 1% to 3%. It can resist corrosive gases, such as chlorine and hydrogen sulfide, reduce metal corrosion, and at the same time improve the cold deformation performance of stainless steel.
Another main component is cobalt, which contains about 1% to 2%. Its main function is to enhance the processability and corrosion resistance of stainless steel. It can also resist corrosion in high-temperature environments and improve the impact strength of metals.
In addition, trace elements in stainless steel include nickel, titanium, aluminum, silicon, etc. These elements can promote the formation of a protective film on chromium, enhance the corrosion resistance of stainless steel, reduce metal corrosion, and improve the mechanical properties of the metal.
Therefore, the main components of stainless steel are alloys of chromium, manganese and cobalt as well as some trace elements. These elements have excellent corrosion resistance and can resist the erosion of a variety of corrosive gases, enhancing the corrosion resistance and mechanical properties of the metal. Its application in the metal processing industry has been widely promoted.
