The technique of refining molten ferronickel is a topic for specialists, [17] and because of ore content variability the processes might even need to be tailored by source: for example the Larco process of Greek ores. [18] "The main reason for adding nickel in ferrous alloys is to promote an austenitic microstructure. Nickel generally increases ...
Ferroaluminum (FeAl) is a ferroalloy, consisting of iron and aluminium.The metal usually consists of 40% to 60% aluminium. Applications of ferroaluminum include the deoxidation of steel, [1] hardfacing applications, reducing agent, thermite reactions, AlNiCo magnets, and alloying additions to welding wires and fluxes.

The history of ferrous metallurgy in the Indian subcontinent began in the 2nd millennium BC. Archaeological sites in the Gangetic plains have yielded iron implements dated between 1800 and 1200 BC. [24] By the early 13th century BC, iron smelting was practiced on a large scale in India. [24]
An iron–nickel alloy or nickel–iron alloy, abbreviated FeNi or NiFe, is a group of alloys consisting primarily of the elements nickel (Ni) and iron (Fe). It is the main constituent of the "iron" planetary cores and iron meteorites.

Ferrophosphorus is a ferroalloy, an alloy of iron and phosphorus. It contains high proportion of iron phosphides, Fe 2 P and Fe 3 P. Its CAS number is 8049-19-2. The usual grades contain either 18 or 25% of phosphorus. [1] It is a gray solid material with melting point between 1050-1100 °C. It may liberate phosphine in contact with water. Very ...
Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. It is important to note, the oxide form may or may not be present once the molten slag solidifies and forms amorphous and crystalline components.
Global steel production grew enormously in the 20th century from a mere 28 million tonnes at the beginning of the century to 781 million tons at the end. [4] Per-capita steel consumption in the US peaked in 1977, then fell by half before staging a modest recovery to levels well below the peak.
