Metallurgical Product Description

Adding molybdenum to steel can make the steel have a uniform fine-grained structure, improve the hardenability of the steel, and help eliminate temper brittleness. In high-speed steel, molybdenum can replace part of tungsten. Molybdenum is widely used in combination with other alloying elements to produce stainless steel, heat-resistant steel, acid-resistant steel, and tool steel, as well as alloys with special physical properties. Molybdenum is added to cast iron to increase its strength and wear resistance.

Product Advantages

Ferromolybdenum is an iron alloy composed of molybdenum and iron. The grade of ferromolybdenum is generally between 55-60. Its main use is as an additive for molybdenum in steelmaking. Adding molybdenum to steel can make the steel have a uniform fine-grained structure, improve the hardenability of the steel, and help eliminate temper brittleness. In high-speed steel, molybdenum can replace part of tungsten.

Manufacture And Use

The most basic definition of the ferromolybdenum production process is that molybdenum is first mined, and then converted into molybdenum (six) oxide MoO3, which becomes a mixed oxide with iron and aluminum oxide, and then is reduced in the thermite reaction. Electron beam melting then purifies the ferromolybdenum, or the product can be packaged as is. Typically, ferromolybdenum alloys are produced from a fine powder, and ferromolybdenum is typically shipped in bags or shipping steel drums.

Ferromolybdenum is an amorphous metal additive in the production process and has several excellent properties that are transferred to the new alloy. One of the main benefits of ferromolybdenum alloy is its hardening properties, making steel extremely weldable. Ferromolybdenum is one of the 5 highest melting point metals in the country. Additionally, adding ferromolybdenum to the alloy can improve corrosion resistance. The characteristics of ferromolybdenum make it an extra layer of protective film on other metals, making it suitable for various products.

Applications

Ferromolybdenum is also used in cars, trucks, locomotives, ships, etc. In addition, ferromolybdenum is used in stainless steel and heat-resistant steels that are employed in synthetic fuel and chemical plants, heat exchangers, generators, refinery equipment, pumps, turbine tubes, ship propellers, plastics and acid, and storage vessels.

Tool steels with a high proportion of ferromolybdenum range are used for high-speed machined parts, cold work tools, drill bits, screwdrivers, molds, chisels, heavy castings, balls, and large drill bits for rolling mills, rolls, cylinder blocks, piston rings.
