In 1860, steel output stood at 13,000 tons. To how much had it expanded by the beginning of the 20th century?

In the 40 or so years to the beginning of the 20th century the steel then blossomed from only 13,000 tons in 1860 to 28 million tonnes which is a huge increase which most likely reflects the impetus given to this production by the Industrial Revolution. This Revolution ran from about 1760-1840 and included I believe the bessemer process of steel making as an innovation from this period.
