STEEL Steel could be produced as early as the mid-1800’s, but the process was expensive. This changed in 1859 when two people (one from Great Britain and one from the U. S.) developed a process (called the Bessemer Process )

Advantages (Bessemer Process) the railroad industry to replaced their old iron rails with stronger steel rails. began to use steel to build buildings and bridges. steel’s resistance to rust made it ideal for used in wire and nails.

Railroads When the price of steel was reduced from 100 dollars to 12 dollars a ton by 1873 railroads could lay more track.
