ferrochromium, alloy of chromium with 30 to 50 percent iron, used to incorporate chromium into steel. It is produced in an electric furnace using chromium ore, iron or iron ore, and carbon, usually anthracite coal. In the intense heat the carbon reduces the metal oxides to the molten alloy, which is poured out into slabs.
