Molybdenum is mainly used for the steel industry, the most of molybdenum is directly used in steel or cast iron in the form of industrial molybdenum oxide block, the less of molybdenum is used in steelmaking in the form of ferromolybdenum. The molybdenum content in low alloy steel is not more than 1%, but the consumption of this aspect accounts for about 50% of the total consumption. Adding molybdenum into stainless steel can improve the corrosion resistance of steel. Adding molybdenum in cast iron can improve the strength and wear resistance of iron. The nickel super alloy containing 18% molybdenum has high melting point, low density, low thermal expansion coefficient and other properties, which is used for making various high temperature components of the aviation and aerospace. Metal molybdenum is widely used in electronic devices such as electronic tubes, transistors, and rectifiers. Molybdenum oxide and molybdate are excellent catalysts in the chemical and oil industries. MoS2 is an important lubricant, used in aerospace and mechanical industry. In addition, due to its unique sulfur resistant properties of MoS2, it can catalyze carbon monoxide to produce alcohols under certain conditions, which is promising C1 chemical catalyst. Molybdenum is one of the essential trace elements in plants, and is used as a trace element fertilizer in agriculture.
Molybdenum tube with high melting point, high strength, good thermal conductivity, high temperature resistance and corrosion resistance can be used for high temperature operating environment above 2000 degrees. Molybdenum tube also can be used in the components of the electron tube, heating high temperature furnace, thermocouple protection tube in high temperature furnace, the supporting parts of the sapphire single crystal furnace and high temperature sintering furnace.
