Tip: the main elements of stainless steel

stainless steel.

Nickel: nickel is the most important core element of stainless steel, which can improve the strength, toughness and hardenability of steel.
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: can improve the strength of steel, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel, high alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties.

chromium: can improve the hardenability and wear resistance of steel, can improve the corrosion resistance and oxidation resistance of steel.

Vanadium: can refine the grain structure of steel, improve the strength, toughness and wear resistance of steel.
When it is melted into austenite at high temperature, the hardenability of steel can be increased.
Conversely, when it is present in the carbide form, its hardenability is reduced.

Molybdenum: can obviously improve the hardenability and heat strength of steel, prevent temper brittleness, improve the remanence and strength.

Titanium: can refine the grain structure of steel, thus improving the strength and toughness of steel.
In stainless steel, titanium can eliminate or reduce intercrystalline corrosion of steel.
Copper: its prominent function is to improve the atmospheric corrosion resistance of ordinary low-alloy steel, especially when used with phosphorus.
