What Is the Chemical Formula of Steel? Sciencing

Apr 11, 2018 · 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.

About 75% of all stainless steel used worldwide is austenitic and about 25% is ferritic. The other families, martensitic, duplex and precipitation hardenable stainless steels each represent less than 1% of the total market. Besides nickel there are other elements that tend to make the structure austenitic. These elements are called austenite formers.
