The history of steel stretches back thousands of years, from the Iron Age when iron began to replace bronze, to today's advanced materials. The breakthrough came in the 19th century with the Bessemer process, which enabled mass production and led to major infrastructure projects. The 20th century saw the development of specialty steels such as stainless steel, which revolutionized industries such as aerospace, construction, and medical technology. Today, steelmaking focuses on sustainability and energy efficiency for the future.
