It is one of the main alloying elements in stainless steel, which mainly imparts corrosion resistance. Steel containing chromium reacts with oxygen to form a very thin and hard chromium oxide film on the surface, protecting the rest of the metal from corrosion.

Nickel enhances the toughness of stainless steel and helps maintain good mechanical properties even at extremely low temperatures. It also plays a role in improving corrosion resistance and processability when alloyed with chromium.

It is a basic component of stainless steel, providing the basic physical properties and structure of steel.

It is used to improve strength and hardness within stainless steel. However, as the carbon content increases, the corrosion resistance of some stainless steels may decrease.

In general, it is an element that must be kept as low as possible in stainless steel. Sulfur improves processability, but it can reduce corrosion resistance.

Manganese is used as a substitute for nickel and contributes to improving the corrosion resistance and strength of stainless steel.

It plays an important role in removing oxides during the manufacturing process of stainless steel. In addition, silicon can improve the strength of alloys.t plays an important role in removing oxides during the manufacturing process of stainless steel. In addition, silicon can improve the strength of alloys.

Phosphorus enhances strength and helps improve the machinability of stainless steel. However, if too much is contained, corrosion resistance may deteriorate.
