Molybdenum is a relatively late discovery of a metal element, 1792 years before the Swedish chemist from the Hui molybdenum ore extracted. Molybdenum metal has been widely used in industry because of its advantages such as high strength, high melting point, Molybdenum Metals corrosion resistance and abrasion-resistant research.
In metallurgical industry, molybdenum is used as an additive for producing various alloy steels, or with tungsten, nickel, cobalt, zirconium, titanium, vanadium, rhenium, etc., Molybdenum Metals to improve its high temperature strength, wear resistance and corrosion resistance. Molybdenum-bearing alloy steels are used for the manufacture of transport devices, locomotives, industrial machinery, and various instruments. Some stainless steels containing molybdenum $number are used in the production of precision chemical instruments and equipment used in seawater environments. High speed steel with 4%~9.5% can be used to manufacture high-speed cutting tools. Molybdenum Metals Molybdenum and nickel and chromium alloys are used to manufacture metal components of aircraft, and corrosion-resistant parts of locomotives and automobiles. The alloys of molybdenum and tungsten, chromium and vanadium are used to manufacture the alloy components and components of warships, tanks, guns, rockets, satellites.
Molybdenum metal is used extensively as heating material and structure material of high-temperature electric furnace, large electrode of vacuum tube and grid, semiconductor and light source material. The thermal neutron trapping section of molybdenum is small and has a high enduring strength, Molybdenum Metals and can also be used as the structural material of nuclear reactors.
In the chemical industry, molybdenum is mainly used for lubricants, catalysts and pigments. Molybdenum disulfide has good lubricating properties and is widely used as additive in oil and grease because of its layered crystal structure and its surface chemical properties. Molybdenum is a catalyst component in the process of hydrogen desulfurization and other petroleum refining, which is used in the oxidation-reduction reaction of ethanol, Molybdenum Metals formaldehyde and oil-based chemicals. Molybdenum Orange is an important pigment pigment. Molybdenum chemical products are widely used in dyes, inks, color precipitation dyes, anti-corrosion primer.
Molybdenum metal in the tube, transistors and rectifiers are widely used in electronic devices. Molybdenum oxide and molybdate are good catalysts in the chemical and petroleum industries. Molybdenum Metals Two molybdenum sulfide is an important lubricant for the aerospace and mechanical industries. Molybdenum is one of the essential trace elements in plants and is used as a microelement fertilizer in agriculture.
The application of molybdenum metal still occupies the most important position in the iron and steel industry. As alloying elements of steel, molybdenum metal can improve the strength, corrosion resistance, abrasion resistance and hardenability, weldability and heat resistance of steels. Molybdenum metal is a good form of carbide elements, in the process of steelmaking is not oxidized, can be used alone can also be used with other alloy elements. The molybdenum consumption of special steels has been increasing regularly, and the consumption of molybdenum metal in special steels has reached 0.201 kg level.
Molybdenum metal molybdenum and chromium, nickel, manganese and silicon can be made of different types of stainless steel, tool steel, high-speed steel and alloy steel. Made of stainless steel has good corrosion resistance, can be used for oil production of corrosion-resistant steel pipe, a molybdenum metal about 6% of stainless steel can also be used to replace titanium for seawater desalination equipment, ocean-going vessels, offshore oil and natural gas mining pipelines. This kind of stainless steel can also be used for car casings, sewage treatment equipment and so on. Molybdenum-containing metal tool steel is twice times more efficient than tungsten tools, Molybdenum Metals with excellent performance, low cost and light weight. Molybdenum metal series High speed steel has the advantages of uneven carbide, abrasion resistance, good toughness and high temperature plasticity, and is suitable for manufacturing molding tools. Molybdenum-containing metal alloy steel can be used to manufacture machine tool structural components, industrial vehicles and bulldozing equipment. Molybdenum-bearing alloy steel with micro pearlite microstructure in rolling condition is an important steel in the construction of railway tracks and bridges.
Molybdenum metal, as an alloy additive of iron, helps to form the matrix of complete pearlite, improves the strength and toughness of cast iron, enhances the uniformity of large castings, and can also improve the quenching property of heat treatment castings. Molybdenum-containing gray cast iron has good abrasion resistance and can be used as brake wheels and brakes for heavy vehicles.
