The Steel City is a common nickname for many cities that were once known for their production of large amounts of steel. With industrial production also in developing countries, like those in Eastern Europe and Asia, most of these cities do not produce as much steel as they used to. It is possible there will be new steel cities in those developing countries.
Sheffield, South Yorkshire, England, United Kingdom; Pittsburgh, Pennsylvania, United States; Pueblo, Colorado, United States; and Newcastle, New South Wales, Australia are the cities most commonly referred to with this name, in their respective countries.
