Metallic chromium is a chemical element with the symbol Cr and atomic number 24. This silvery-gray metal belongs to the transition metals and is characterized primarily by high hardness as well as good resistance to corrosion and oxidation.

The main industrial significance of chromium is related to its use as an alloying element. The addition of chromium makes it possible to significantly improve the corrosion resistance and oxidation resistance of steels and other alloys. Therefore, chromium is an important component of many stainless steels and heat-resistant special alloys.

Metallic chromium is also used for the production of special coatings, alloys, and engineering materials. Depending on the application, various purity grades and delivery forms are available, including lumps, granules, and powder.
