Who invented high grade steel?

Answer 1

High-grade steel, often referred to as crucible steel, was developed in ancient India around 300-500 AD, notably with the production of Wootz steel. This method involved creating high-quality steel through a complex process of smelting iron with carbon-rich materials. The technique was later refined and popularized in the 19th century by figures like Sir Henry Bessemer, who invented the Bessemer process, enabling mass production of steel with improved quality.
