Strong yet flexible, steel is the metal that powers society. The program considers how engineers use the Bessemer process to produce high-quality steel used in everything from battleships to bicycles. Architects discuss the importance of steel's tensile strength in bridge construction, and workers at a recycling plant reveal how steel recycling saves millions of dollars as well as millions of kilowatt hours of electricity.
