Andrew Carnegie focused on building the country’s infrastructure via the steel industry

It became obvious that Andrew Carnegie possessed the inclinations and skills necessary to innovate and maximize his company. As an illustration, he was able to successfully implement the Bessemer steel production method, which reduced costs across the board for the steel sector. The extensive network of skyscrapers, bridges, trains and ships in the country was built in part thanks to Carnegie's steel companies.

His steel industry provided the raw materials needed to construct the US's physical infrastructure. Andrew Carnegie manufactured the steel that made machinery and transportation possible across the country, which served as a spark for America's participation in the Industrial Revolution. He also invented the machine called the "Bessemer Converter" that could swiftly and effectively turn molten iron into stronger steel, which is one of the interesting facts about Andrew Carnegie.

His steel sector quickly grew to dominate a sizable portion of the world steel market. The US had surpassed the UK in steel production by the late 1880s. His business partnership with J.P. Morgan, a banker, resulted in the establishment of the U.S. Steel Corporation in 1901, which grew to be one of the biggest corporations in the world. Over time, his main focus and his strategy revolutionized steel production and accelerated the growth of the American economy.
