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 …
Chromium, as trivalent (+3) chromium, is a trace element that is naturally present in many foods and available as a dietary supplement. Chromium also exists as hexavalent (+6) chromium, a toxic by-product of stainless steel and other manufacturing processes [ 1, 2 ]. This fact sheet focuses entirely on trivalent chromium.
