Application of relevant Molybdenum types 

Molybdenum is one of the most effective alloying agents, of which about 80% is used in the production of various types of steel such as structural steels, stainless steels, high speed steels, tool steels and many more. Molybdenum-based alloys offer a unique combination of mechanical properties, including high strength at elevated temperatures, high thermal and electrical conductivity with low thermal expansion.

Ferromolybdenum (FeMo):

Ferromolybdenum is an alloying agent that is produced by reducing MoOx together with iron oxide in an aluminothermic reaction. FeMo is commercially available in the form of lumps with a grain size of 5-50mm, with a molybdenum content between 60 wt% and 75 wt%. FeMo can be added during both cast iron and steel production, whereby more than 80% is consumed by the steel industry for the production of stainless and high-alloy steels.

Molybdenum Oxide Briquettes / Powder (MoOx Briqs / Powder):

Molybdenum oxide (MoOx) is the basis from which nearly all commercial molybdenum products such as Ferromolybdenum (FeMo), molybdenum metal, or chemical molybdenum oxide are produced through further processing. However, it can also be used directly as an alloying agent, where it is charged together with steel scrap to ensure the desired molybdenum content (usually 55 wt% and 65 wt%). MoOx comes in the form of powder which can be further processed into briquettes which are easier to handle by many steel plants. Around 30% to 40% of MoOx produced is converted into FeMo by processing plants.

Molybdenum Metal (Mo Metal): 

Pure molybdenum can be obtained from MoOx by further hydro- and pyrometallurgical processing. Molybdenum metals are available in numerous shapes and forms such as rods, bars, tubes, sheets, plates, discs, squares, and wires.
