The manufacture of stainless steel involves a series of processes. First, the steel is melted, To make stainless steel, the raw materialsâiron ore, chromium, silicon, nickel, etc.âare melted together in an electric furnace. This step usually involves 8 to 12 hours of intense heat. Next, the mixture is cast into one of several shapes, including blooms, billets, and slabs. and then it is cast into solid form.
Iron ore Steel is an alloy consisting mostly of iron and less than 2% carbon. Iron ore is, therefore, essential for the production of steel, which in turn is essential in maintaining a strong industrial base. 98% of mined iron ore is used to make steel.Iron is one of the most abundant metallic elements.oke, made by carburising coal (i.e. heating in the absence of oxygen at high temperatures), is the primary reducing agent of iron ore. Coke reduces iron ore to molten iron saturated with carbon, called hot metal. Fact sheetsteel and raw materials Efficient use of natural resources is critical to sustainability.
