24Cr Chromium

Description

Named from the Greek word meaning “color,” chromium is a lustrous, hard, bluish-gray metal. It can be polished to a mirror-like finish and is often used as a decorative and protective plating or finish. Like vanadium, chromium hardens steel, so it is frequently used in alloys, especially stainless steel. Chromium compounds are all strongly colored, and this characteristic gives chromium its name. Chromium compounds are used as a yellow coloring agent in the textiles industry. It also is used in the tanning of leather. Rubies and emeralds gain their color from chromium impurities.
