Chromium was discovered by Louis Vauguelin in 1798 and was first obtained, in its elemental form in 1859, by WHOLER. However, chromium as a commercial metal, was subsequently established as a medium for the introduction of chromium into steel, to get the required beneficial effects of Chromium imparted to Steel. Chromium increases the hardness, strength, yield point, elasticity and resistance to corrosion, heat, acid, etc. Therefore, chromium is essentially used for the production of all varieties of stainless steels: Heat & Acid Resistant Steels: Structural, Tools & other special categories of steels. Chromium steels are also used for the manufacture of Ball and Roller bearings.
