What Is the Chemical Formula of Steel? Sciencing
Steel is a mixture of iron and carbon fused together with one or more other metals or nonmetals. Because steel is a mixture rather than a chemical compound, steel does not have a set chemical compound formula. The naming convention for steel depends upon the steel’s composition—what is mixed in with the iron—such as carbon steel or tungsten steel.
