Femo60% 65% 70% Ferromolybdenum Ferro Molybdenum For Welding Materials

Ferro Molybdenum is a hardening agent and is found in many alloy steels that are heat-treatable. Molybdenum prevents corrosion in stainless steels and alloy steels. The steel industry is the largest user of molybdenum, accounting for approximately 80% of molybdenum mined in the world.

Molybdenum is used to improve mechanical and physical properties of all kinds of steels. Applications for our products include additions to constructional alloy steels, tool and high speed steels, stainless steels, super alloys and cast irons as well as cast steels. It is also used in production of welding electrodes.

Between thirty and forty percent of moly tech oxide production is processed into ferromolybdenum (FeMo). The oxide is mixed with iron and reduced by aluminium in presence of Ferro Silicon in a thermite reaction, producing a ferromolybdenum ingot weighing several hundred kilograms. The product contains between 60 and 65% molybdenum, balance essentially iron. After air cooling, the ingot is crushed and screened to meet specified ferromolybdenum particle size ranges.

Manufacturing Process
The ferromolybdenum manufacturing process begins with molybdenum being mined and transformed into molybdenum (VI) oxide (MoO3). MoO3 is mixed with iron oxide and aluminum and then reduced by an aluminothermy reaction.
Electron-beam melting is applied to purify the ferromolybdenum. The final alloy product is produced in the form of small briquettes or fine powder. Ferromolybdenum is usually supplied in bags or steel drums. 

Applications
The largest application area of ferromolybdenum is in the manufacture of ferrous alloys. Based on the range of molybdenum content, ferromolybdenum can be applied in the manufacture of machine tools and equipment, military hardware, refinery tubing, load-bearing parts and rotary drills.

Ferromolybdenum is also used in cars, trucks, locomotives and ships. Ferromolybdenum is added to stainless and heat-resisting steels that are used in synthetic fuel and chemical plants, heat exchangers, power generators, oil-refining equipment, pumps, turbine tubing, ship propellers, plastics and inside acid storage containers.

Tool steels that contain a higher percentage of ferromolybdenum are used in high-speed machining parts, drill bits, screwdrivers, dies, cold work tools, chisels, heavy castings, rolls, cylinder blocks, ball and rolling mills, piston rings and large drill bits.
