Molecular Weight: 349.32. CAS Number: 21679-31-2 Chromium Metal: Chromium metal is primarily used for its ability to help steel resist corrosion and increase hardness. What we commonly refer to as stainless steel is actually composed of over 13.5 percent chromium. The metal can be produced using three methods: (1) an aluminothermic process, (2) a silicothermic process, or (3), an electrolytic process. Basic chromium sulfate Cr (OH)SO4, or chromium hydroxide suflate, is made via the reduction of sodium dichromate solution with sulfuric acid or sulfur dioxide.

It is the first element in group 6. It is a steely-grey, lustrous, hard, and brittle transition metal.
