Molybdenum briquettes are mainly used in iron and steel industry, most of which are directly used in steelmaking or cast iron in the form of industrial molybdenum oxide briquettes, and a few are smelted into ferromolybdenum and then used in steelmaking. The molybdenum content in low alloy steel is not more than 1%, but the consumption in this aspect accounts for about 50% of the total molybdenum consumption. Adding molybdenum to stainless steel can improve the corrosion resistance of steel. Adding molybdenum to cast iron can improve the strength and wear resistance of iron.
Nickel-based superalloy containing 18% molybdenum has the characteristics of high melting point, low density and small thermal expansion coefficient, for manufacturing various high-temperature components in aerospace industry.
