5. The Bessemer process The whole concept of steel changed dramatically in the nineteenth century. An entirely new constructional material was discovered: low—carbon steel, strong, ductile, tough, not quench—hardenable but capable of being produced and shaped by mechanical working cheaply on an enormous scale. The modern age of steel was begun. The starting point was an experiment
