The role of molybdenum products in the steel industry is extraordinary!


Temperature strength and corrosion resistance. Currently, it is widely used in fields such as aerospace, weapons, electronics, and glass.

The application of molybdenum products in the steel industry still occupies a major position. Molybdenum, as an alloying element in steel, can improve its strength, especially at high temperatures and toughness; Improve the corrosion resistance of steel in acid alkali solutions and liquid metals; Improve the wear resistance and hardenability, weldability, and heat resistance of steel. The efficiency of molybdenum containing tool steel is twice that of tungsten tools, with excellent performance, low cost, and light weight.

The role of molybdenum products in steel such as alloy steel, stainless steel, and tool steel is as follows:

1. Reduce tempering brittleness;

2. Resistance to hydrogen embrittlement;

3. Improve high-temperature strength;

4. Resistance to stress cracking caused by sulfides;

5. A hard martensite structure can be obtained by reducing the proper value of cooling rate * * *, thus improving the strength, hardness and toughness of large cross-section components;

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

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 steel. It can enhance the strength, hardness, weldability, and toughness of alloys, as well as enhance their high-temperature strength and corrosion resistance. Rich molybdenum resources. Molybdenum, like tungsten, is a refractory rare metal. Molybdenum has a melting point of 2620 ℃, and its strength is high at both room and high temperatures due to its strong interatomic bonding. It has a small coefficient of expansion, high conductivity, and good thermal conductivity. At room temperature, it does not react with hydrochloric acid, hydrofluoric acid, or alkaline solutions, 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 extensive applications and good prospects in important sectors such as metallurgy, agriculture, electrical, chemical, environmental protection, and aerospace, becoming an important raw material and irreplaceable strategic substance in the national economy.
