Metal elements and functions required in the production of stainless steel:Nickel: Nickel is a very important core element in stainless steel. It can improve the strength and toughness of steel and improve hardenability. When the content is high, some physical properties of steel and alloy can be significantly changed, and the corrosion resistance of steel is improved.
Molybdenum: It can significantly improve the hardenability and heat resistance of steel, prevent tempering brittleness, and improve remanence.
Titanium: It can refine the grain structure of steel and increase the strength and toughness of steel. In stainless steel, titanium can eliminate or reduce the intergranular corrosion of steel.Copper: Its outstanding effect is to improve the atmospheric corrosion resistance of ordinary low alloy steel, which is more significant when used with phosphorus.
