The Bessemer Steel process is the way of removing impurities from iron to make steel. A blast of hot air on molten iron removed iron particles. Industry needed steel but the process being used was costly and time consuming.
Steel manufacturing increased through the building of steel bridges, steel buildings, steel railroads, and weapon production.
The steel industry provided jobs in factories which helped in the growth of cities. New products are bought by consumers who are also workers in factories.
