The inorganic material that are derived from earth's crust used to support our civilisation. Chromium is one of such very important metal, although it is very rarely used in its metal form, is an essential ingredient for stainless steel making. tool, and alloy steel, nickel–chromium heating elements, and plating metals.
Ferrochrome (FeCr) is the main source of chromium (Cr) units used in modern-day chromium (Cr) containing alloys. The vast majority of produced Cr is used during the production of stainless steel, which owes its corrosion resistance mainly to the presence of Cr. In turn, stainless steel is mainly produced from Cr-containing scrap …
