Steel is a discovery of the Iron Age, a period that started around 1200 BCE. Iron ore was first mined in Central Asia and Europe, and humans at this time used iron to make tools and weapons in a practice called ferrous metallurgy. Iron products evolved during this time, beginning with blacksmiths producing wrought iron goods.

The steel industry contributes around 8% of the world's carbon emissions and is largely (73%) reliant on blast furnace and basic oxygen furnace (BOF) technologies to separate oxygen from the iron oxides that make up iron ore and produce the strong, permanent material known as steel. Making steel involves several applications of extreme heat.

India's steel production is estimated to grow 47% to 123127 MT in FY24. The growth in the Indian steel sector has been driven by the domestic availability of raw materials such as iron ore and costeffective labour. Consequently, the steel sector has been a major contributor to India's manufacturing output.
