The iron age began in Southwest Asia ca. 1000 BC, once smelting pit designs had advanced sufficiently to produce the higher temperatures needed to smelt iron ore (see Iron Smelting). 9 In about five centuries, it covered the east-west span of Eurasia. Thus, by ca. 500 BC, most of Eurasia had transitioned to the iron age. 27,28 Use the easy navigation links below. Carbon Steel, Alloy Steel, Stainless Steel, Tool Steel.
