To determine

The invention of economical production method of the steel.

Explanation of Solution

Steel has been the most used material in the structures for a few centuries. The production of steel was quite expensive compared to other materials. In earlier days of the nineteenth century, the American inventors started processes which can produce the steel economically. The process was named as Bessemer process. By this process, the steel production cost reduced to 82% to the previous cost. So, this is the first economical production method invention in steel according to the production cost.

Therefore, we can say that economic production of steel started in the early 19th century.
