Bessemer process - Wikipedia

The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.

Iron: From mythical to mundane - The Roots of Progress

Oct 22, 2019  Today, we know that iron with less than about 0.1% carbon is wrought iron, with more than 2.1% it is cast iron, and in the sweet spot in between lies steel, the Goldilocks of iron-carbon alloys. The task of refining cast iron, then, is to remove the excess carbon. But in the early 1850s, the best methods for this took days or weeks.

Wrought iron - Wikipedia

Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded.
