Ferroboron (CAS Registry Number 11108–67-1) is a ferroalloy of iron and boron with boron content between 17.5 and 20%.[1]It is manufactured either by carbothermic reduction of boric acid in an electric arc furnace together with carbon steel, or by the aluminothermic reduction of boric acid in the presence of iron.

Boron is effective at very low concentrations – 30 ppm B can replace an equivalent 0.4% Cr, 0.5% C, or 0.12% V. [2] 30 ppm B has also been shown to increase depth of hardening (~ +50%) in a low-alloy steel – thought to be due to its retardation of austenite decomposition to softer bainite, ferrite, or pearlite structures on cooling from an ...
Silicon ferroalloy consumption is driven by cast iron and steel production, where silicon alloys are used as deoxidizers. Some silicon metal was also used as an alloying agent with iron. On the basis of silicon content, net production of ferrosilicon and miscellaneous silicon alloys in the US was 148,000 t in 2008.
