These are the elements listed in stainless steel tubes:

Nitrogen: It is used to stabilize the austenitic structure of stainless steel, which enhances its resistance to pitting corrosion and strengthens the steel.

Titanium and Miobium: Titanium and Miobium are used to reduce the sensitization of stainless steel. When stainless steel is sensitized, intergranular corrosion can occur.

Copper and Aluminum: Copper and Aluminum, along with Titanium, can be added to stainless steel to precipitate its hardening. Hardening is achieved by soaking at a temperature of 900 to 1150 F. These elements form a hard intermetallic microstructure during the soaking process at the elevated temperature.

Sulfur and Selenium: Sulfur and Selenium are added to 304 stainless to make it machine freely.
