USA HISTORY

Detailed explanation-1: -Essentially, the Bessemer Process allowed for the production of cheaper and high quality steel. This quality steel replaced iron as the preferred metal for railroad rails. So, cheaper and longer lasting steel for rails was how the Bessemer Process helped westward expansion in US history.

Detailed explanation-2: -The Bessemer process allowed steel to be produced without fuel, using the impurities of the iron to create the necessary heat. This drastically reduced the costs of steel production, but raw materials with the required characteristics could be difficult to find.

Detailed explanation-3: -The engineer and inventor Henry Bessemer revolutionised steel production thanks to an air-based iron decarbonization system. He was able to cut costs and manufacture a stronger and lighter steel on a large scale. A breakthrough that fueled the expansion of the railroad and marked the birth of modern cities.

Detailed explanation-4: -The Bessemer Process was an extremely important invention because it helped made stronger rails for constructing the railroads and helped to make stronger metal machines and innovative architectural structures like skyscrapers.
