Chromium is a bluish-white hard metal. Very pure chrome is machinable. It is found in nature in its pure form and is widely used in various branches of science, technology and production. Most often, chromium is used as a component of alloys that are used in the manufacture of medical or chemical technological equipment and devices.

Chromium is an important component in many alloy steels (in particular, stainless steel), as well as in a number of other alloys. The addition of chromium significantly increases the hardness and corrosion resistance of the alloys. The use of Chromium is based on its heat resistance, hardness and corrosion resistance. Most of all Chromium is used for smelting chromium steels. Aluminum and silicothermic Chromium is used to smelt nichrome, nimonic, other nickel alloys and stellite.
A significant amount of Chromium is used for decorative corrosion-resistant coatings. Powdered Chromium is widely used in the production of cermet products and materials for welding electrodes. Chromium in the form of Cr3 + ion is an impurity in ruby, which is used as a gemstone and laser material. Chromium compounds are used to etch fabrics during dyeing. Some Chromium salts are used as an integral part of tanning solutions in the leather industry; PbCrO4, ZnCrO4, SrCrO4 - as artistic paints. Chromite-magnesite refractory products are made from a mixture of chromite and magnesite.
It is used as a durable and beautiful electroplated coating (chrome plating).
Chromium is used for the production of alloys: chromium-30 and chromium-90, which are indispensable for the production of powerful plasma torches nozzles and in the aerospace industry.
