Chromium Metal
Chromium is a lustrous, brittle, hard metal. Its colour is silver-gray, and it can be highly polished. It does not tarnish in air, when heated it burns and forms the green chromic oxide. Chromium is unstable in oxygen; it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below.

Application:
Improves the oxidation resistance and hardenability and good wear resistance in stainless steel castings.
Some of the application of Chromium metal is in A) Alloying, B) Steel, C) Chemical Industry & D) Auto mobile industry.
Chromium metal is valued for its high corrosion resistance and hardness. A major development in steel production was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel
chrome plating (electroplating with chromium) together comprise 85% of the commercial use. Chromium is also greatly valued as a metal that is able to be highly polished while resisting tarnishing.
