A practical, accessible account traces the development, raw materials, and manufacturing methods of iron and steel for a general reader. It surveys early smelting and modern blast-furnace practice, details ores, coke, and fluxes, and explains conversion processes including puddling, Bessemer, and open-hearth, plus casting, malleable iron, alloy and high-speed steels. Chapters cover mechanical processing—rolling, wire drawing, and tube manufacture—and describe heat treatment, microstructural transformations, and the iron–carbon equilibrium diagram. Illustrated explanations and selected references clarify industrial applications, material properties, and the relationships among iron and steel products.
