What is the use of molybdenum?

Molybdenum is mainly used in the steel industry, most of which is used directly in the post-industrial molybdenum oxide briquette steel or cast iron, molybdenum iron smelting small part and then used in steelmaking. Low alloy steel molybdenum content of not more than 1%, but this aspect of consumption accounts for about 50% of the total consumption of molybdenum. Stainless steel, molybdenum is added, can improve the corrosion resistance of steel. Join molybdenum metals in cast iron, iron can improve the strength and wear resistance. Nickel-base superalloy containing 18% molybdenum have high melting point, low density and thermal expansion coefficient and other characteristics, used in the manufacture of various high-temperature aerospace components.
