The chemical composition of steel can vary greatly

In practice, steel often contains different alloying elements, such as manganese, nickel, vanadium, etc., depending on its use. The application and study of steel has a long history, but until the invention of the Bechner steelmaking method in the 19th century, steel production was a costly and inefficient task.
