The stainless steel fork that you eat your food with contains chromium. Chromium metal is also widely used as a catalyst and its compounds are sought after as pigments, for their bright green, yellow, red, purple, black and orange hues. Other applications of the material include the tanning of leather, the making of dyes and wood preservatives. Chromium (Cr), chemical element of Group 6 (VIb) of the periodic table, a hard steel-gray metal that takes a high polish and is used in alloys to increase strength and corrosion resistance. Se hela listan på chemicool.com The free chromium produced in this reaction is laid down in a thin layer on the surface of another metal, such as steel.

Chromic acid is a powerful oxidizing agent and is a useful compound for cleaning laboratory Chromium steels are types of steel, with which iron can be alloyed with chromium. Colloquially the term is often used interchangeably with the word stainless steel.
