In 1916, stainless steel revolutionized technology through the pioneering work of English metallurgist Harry Brearley. By adding chromium to molten iron, Brearley produced a rust-resistant alloy, transforming industries like cutlery manufacturing, architecture, transportation, and healthcare. This innovation not only improved product durability and corrosion resistance but also promoted sustainable manufacturing practices. The introduction of stainless steel marked a pivotal advancement in engineering and materials science.
