What Is the Chemical Formula for Stainless Steel?

Stainless steels are iron alloys that contain 10.5 percent chromium and can be enhanced with other metals, such as copper, titanium, molybdenum and nickel. Stainless steel can also be improved for various applications by adding non-metals to its structure, such as nitrogen and carbon. The chromium-rich oxide layer on the surface of the steel makes for an alloy that is easily repairable.

Stainless steel is an alloy that is more effective in resisting corrosion, stains and rust, when compared to ordinary steel. For example, unprotected carbon steel rusts easily, when exposed to moisture and air. Once the iron oxide film, or rust, sets in, corrosion of the metals surface is imminent. Stainless steel is used to construct bridges, buildings, automobiles, firearms, monuments, locomotives, airplanes and many other things we use and depend upon in everyday life. Stainless steel is also 100 percent recyclable.
