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 distinguished primarily by its high hardness as well as good corrosion resistance and oxidation resistance.
The main industrial importance of chromium is associated with its use as an alloying element. The addition of chromium significantly improves 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.
