Molybdenum is a metallic element commonly used as an additive in alloys and stainless steels. Molybdenum has the advantages of high melting point and boiling point, good high temperature strength, anti-friction and corrosion resistance, high thermal conductivity, small thermal expansion coefficient and good hardenability. It can enhance the strength, hardness, weld ability and toughness of the alloy, as well as its high temperature strength and corrosion resistance. Currently, molybdenum is widely used in aerospace, weapons, electronics, glass and other fields.

The application of molybdenum products in the steel industry still occupies the most important position. As an alloying element of steel, molybdenum can improve the strength of steel, especially high temperature strength and toughness; improve the corrosion resistance of steel in acid-base solution and liquid metal; improve the wear resistance of steel and improve hardenability and weldability and heat resistance. Molybdenum-containing tool steels are twice as efficient as tungsten tools, providing excellent performance, low cost and light weight.

The role of molybdenum products in gold steel, stainless steel, tool steel and other steels is as follows

1. Reduce temper brittleness

2. Anti-hydrogen embrittlement;

3. Improve high temperature strength;

4. Stress cracking resistance caused by sulfide;

5. Reduce the cooling rate to an appropriate value to obtain a hard martensite structure, thus improving the strength, hardness and toughness of large-section members;

6. Improve the corrosion resistance of stainless steel, especially against chloride pitting;

7. Improve the welding performance of high-strength low-alloy steel 

Molybdenum is a metallic element commonly used as an additive in alloys and stainless steels. It can enhance the strength, hardness, weld ability and toughness of the alloy, as well as its high temperature strength and corrosion resistance. Rich molybdenum resources. Like tungsten, molybdenum is a refractory rare metal. The melting point of molybdenum is 2610°C. Due to the strong interatomic bonding force, its strength is very high at room temperature and high temperature. It has a small expansion coefficient, high electrical conductivity and good thermal conductivity. It does not react with hydrochloric acid, hydrofluoric acid and alkali solution at room temperature, but only dissolves in nitric acid, aqua regia or concentrated sulfuric acid. It is also quite stable for most liquid metals, non-metallic slag and molten glass. Therefore, molybdenum and its alloys have a wide range of applications and good prospects in important sectors such as metallurgy, agriculture, electrical, chemical, environmental protection and aerospace, and become an important raw material and irreplaceable strategic substance in the national economy.
