Production of Stainless Steel Part One Total Materia

Because the strong affinity of chromium for carbon, all pneumatic processes for refining stainless steel attempt to achieve selective oxidation of carbon in the presence of chromium by raising the reaction temperature and/or reducing the partial pressure of CO by vacuum or mixed gas (argon oxygen) refining.

From ore to steel ArcelorMittal

In a basic oxygen furnace, molten iron ore is the principal raw material and is mixed with varying quantities of steel scrap and alloys to produce different grades of steel. In an electric arc furnace, recycled steel scrap is melted directly into new steel. About 12% of our steel is made from recycled steel.
