~300 BCE: South Asian metalworkers produce crucible steel
By about 300 BCE, and possibly earlier, metalworkers in southern India were making high-carbon steel by heating iron with carbon-bearing materials in crucibles. Known later as wootz, the steel entered long-distance trade and supplied the material for many blades subsequently called Damascus steel.

A treatise published in Prague described converting wrought iron to steel by heating it in contact with charcoal. The cementation process added carbon without melting the iron and became an important source of European tool steel.

Benjamin Huntsman developed a method near Sheffield for melting blister steel in closed crucibles and casting the liquid into molds. The more uniform steel suited demanding tools and helped establish Sheffield as a center of steel production.

Henry Bessemer publicly described blowing air through molten pig iron to remove carbon and other impurities. Subsequent improvements made steel available in large batches at much lower cost, expanding its use in railway rails, machinery, and structures.

Pierre-Émile Martin used William Siemens's regenerative furnace to make steel. The open-hearth process allowed producers to melt scrap with pig iron and adjust the composition during a relatively slow heat, giving manufacturers greater control over quality.

Sidney Gilchrist Thomas and Percy Gilchrist patented a basic lining for the Bessemer converter that enabled phosphorus removal. The process made previously unsuitable iron ores useful for steelmaking, especially in continental Europe, while producing a fertilizer-rich slag.

Robert Hadfield developed a manganese-rich steel that combined toughness with resistance to wear. The alloy found uses in railway crossings, mining machinery, and other parts exposed to repeated impact, expanding the properties available from industrial steels.

Halcomb Steel of Syracuse, New York, tapped the first heat from its Héroult electric arc furnace in April 1906, which an ASM landmark designation calls the first electric arc steelmaking furnace in the Western Hemisphere. Electric heating initially served specialty steels and later supported mills that melted scrap without operating their own blast furnaces.

Tata Iron and Steel Company produced its first steel ingot at Sakchi, later renamed Jamshedpur. The integrated works established a major Indian source of rails and structural steel and became a center of industrial development under colonial rule.

Harry Brearley produced a chromium-containing steel in Sheffield that resisted corrosion while investigating gun-barrel materials. Its suitability for cutlery helped commercialize stainless steel, alongside related alloy developments elsewhere in Europe.

The Austrian steelworks at Linz began commercial production using oxygen blown into molten iron. Developed from Robert Durrer's experiments, the process refined large batches much faster than open-hearth furnaces and spread through the global steel industry.

Steelmakers increasingly cast molten steel directly into continuous strands instead of individual ingots. Adoption in Japan and other industrial countries reduced intermediate handling and reheating while improving metal yield and consistency.

Nucor began steelmaking at Darlington, South Carolina, using an electric arc furnace to melt scrap into steel bars. The plant helped establish the company's mini-mill model, which entered markets with smaller facilities and lower capital requirements than integrated works.

Pohang Iron and Steel Company completed the first phase of its integrated works in South Korea. The complex supplied an expanding manufacturing economy and became part of the shift toward large, modern steelmaking facilities in East Asia.
https://en.wikipedia.org/wiki/POSCO1989: Nucor commercializes thin-slab steel casting
Nucor's Crawfordsville plant in Indiana began producing flat-rolled steel using thin-slab casting. Combining the technique with electric arc steelmaking allowed mini-mills to enter sheet markets that had largely belonged to integrated producers.

China's annual crude steel production reached about 100 million metric tons. Industrial expansion and subsequent growth in construction and manufacturing made Chinese demand and production increasingly important to the world steel market.

The Hydrogen Breakthrough Ironmaking Technology (HYBRIT) project supplied hydrogen-reduced iron for trial steel delivered to Volvo Group. The Swedish demonstration replaced coal in the reduction step, testing a route to lower emissions from ore-based steel.
