Stainless steel as a more value-added special steel products, its application field is more and more extensive, whether in the civilian field such as decoration, kitchen utensils, household appliances, etc., or industrial fields such as petrochemical, machinery and equipment have been widely used, the current high-quality stainless steel products market prospects are still promising. Below, let's take a look at the functions of the main related elements required for the production of stainless steel:
Chromium Cr: can improve the hardenability and wear resistance of steel, can improve the corrosion resistance and oxidation resistance of steel.
Nickel Ni: The most important core element of nickel stainless steel, which 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 can be improved.
Manganese Mn: can improve the strength of steel, can reduce and eliminate the adverse effects of sulfur, and can improve the hardenability of steel, high alloy steel with high manganese content (high manganese steel) has good wear resistance and other physical properties.
Molybdenum Mo: can obviously improve the hardenability and thermal strength of steel, prevent temper brittleness, improve remanence and Jiao jiao.
Titanium Ti: can refine the grain structure of steel, thereby improving the strength and toughness of steel. In stainless steel, titanium can eliminate or reduce the intergranular corrosion of steel.
Vanadium V: can refine the grain structure of steel, improve the strength, toughness and wear resistance of steel. When it is fused into austenite at high temperature, it can increase the hardenability of the steel; On the contrary, when it is present in the carbide form, it will reduce its hardenability.
Copper Cu: Its outstanding role is to improve the atmospheric corrosion resistance of ordinary low alloy steel, which is more obvious when used with phosphorus
