What is Ferromolybdenum?
An essential iron-molybdenum metal alloy, ferromolybdenum is mainly used to alloy high-strength low-alloy (HSLA) steel. It has a 60–75% molybdenum concentration. Iron, aluminium, and molybdenum (VI) oxide (MoO3) are heated to create the alloy. Molybdenum is produced in situ when the oxide and aluminium join through an aluminothermic process. Ferromolybdenum can be utilised directly or refined via electron beam melting. Before casting, it is added to molten steel to add molybdenum to the alloy.
The physical properties and applications of ferromolybdenum are as follows: Physical Properties: Appearance: 9 g/cm; Melting Point: 1665–1715 °C; Applications: The most common use of ferromolybdenum is in the production of ferrous alloys, which include military hardware, load-bearing structures, machine tools and equipment, and refinery tubing. Additionally, it is used in the production of stainless steel and other special types of steel that must withstand high temperatures. Finally, ferromolybdenum is frequently added to steel and cast iron to improve their hardenability, strength, and resistance to corrosion.
Manufacturing Process
There are multiple steps in the ferromolybdenum manufacturing process:
Molybdenum (VI) oxide (MoO3) is produced by mining molybdenum.
MoO3 is combined with aluminium and iron oxide.
An aluminothermic process reduces the mixture.
Ferromolybdenum is purified by electron-beam melting.
The finished alloy product is often supplied in bags or steel drums and is created as tiny briquettes or fine powder.
What is Ferromolybdenum 70?
An iron-molybdenum alloy called Ferromolybdenum 70 has a molybdenum concentration of roughly 70%. It is frequently employed in many different contexts.
Production Process: A combination of iron, aluminium, and molybdenum (VI) oxide (MoO3) is heated to create ferromolybdenum 70. Molybdenum is produced in situ when the oxide and aluminium react together through an aluminothermic process. The resultant alloy can be utilized directly or refined further using techniques such as electron beam melting.
Steel Alloying: A major source of molybdenum for alloying high-strength low-alloy (HSLA) steel is ferromolybdenum 70. Known for its enhanced mechanical qualities, HSLA steel finds application in a number of sectors, such as the construction, oil and gas, and automotive industries.
Heat Resistance: Steel’s resistance to high temperatures is enhanced when ferromolybdenum 70 is added. Because of this, it can be used in high-temperature settings for things like heat-resistant components and equipment.
