Ferromolybdenum is an alloy of iron and molybdenum used primarily as an alternative additive in producing alloy steels, cast irons, and nonf errous alloys.
Ferromolybdenum is a ferroalloy containing up to 60 percent molybdenum. Two plants converted molybdenite concentrate to molybdic oxide, which was used to produced ferromolybdenum, metal powder, andother molybdenum compounds. The hard particles are composed of 60 to 70% molybdenum and the reminder of iron. The hard particles are formed and dispersed into the matrix as ferromolybdenum hard particles, resulting in the improvement of the wear resistance. Boron has a smaller atomic radius and is added in an amount in the range of 0.3 to 1% to the ferromolybdenum hard particles. Steel producers add molybdenum as oxide or ferromolybdenum to increase high – temperature performance resist sulfide stress cracking, improve corrosion ressistance, improve wear ressistance. The market scenario for noble alloys - mainly ferrovanadium and ferromolybdenum - eased notably over the course of the year and settled at US-$ 67,000, after prices for ferromolybdenum had peaked at US-$ 100,000 (May 2005) per ton of pure molybdenum.
