  • What Is the Origin of Iron Sciencing

    May 02 2018 · Iron continued as the key metal fabric in human civilization until the 1850s when innovators began to learn that if a bit more carbon was added to iron during the production process a durable yet flexible metal resulted. By the 1870s production innovations made this new metal alloy called steel more economically viable to mass produce.
