What were two new methods of making steel and how did they change that industry?

Two significant methods of making steel are the Bessemer process and the open-hearth process. The Bessemer process, developed in the 1850s, allowed for the mass production of steel by blowing air through molten iron to remove impurities, significantly reducing costs and time. The open-hearth process further improved steel production by enabling larger quantities of steel to be produced more consistently, which helped meet the growing demands of the industrial revolution and transformed industries like construction and manufacturing. Together, these innovations made steel more accessible and affordable, fueling advancements in infrastructure and technology.
