The role of molybdenum boat in iron and steel manufacturing industry is extraordinary

Molybdenum boat is a metal element, which is generally used as an additive for alloy and stainless steel. Molybdenum boat has the advantages of high melting point and boiling point, good high temperature strength, friction resistance and corrosion resistance, high heat conductivity, small coefficient of thermal expansion, and good hardenability. It can enhance the strength, hardness, weldability and resistance of the alloy, as well as its high temperature strength and corrosion resistance. Now it is widely used in aerospace, weapons, electronics, glass and other fields.

The use of molybdenum boat products in the iron and steel industry still occupies a major position. As the alloying element of steel, molybdenum boat can improve the strength of steel, especially the high temperature strength and resistance; Improve the corrosion resistance of steel in acid alkali solution and liquid metal; Improve the wear resistance of steel and improve the hardenability, weldability and heat resistance. The power of tool steel containing molybdenum boat is twice that of tungsten tool, with excellent function, low cost and light weight.

The role of molybdenum boat products in alloy steel, stainless steel, tool steel and other steels is as follows:
1. Reducing temper brittleness;
2. Resistance to hydrogen embrittlement;
3. Improve high temperature strength;
4. Resistance to stress cracking caused by sulfide;
5. A hard martensite arrangement is obtained by decreasing the cooling rate to an appropriate value, thereby improving the strength, hardness and resistance of large section members;
6. Improve corrosion resistance of stainless steel, especially chloride pitting;
7. Improve the welding function of high-strength low alloy steel.

Molybdenum boat is a metal element, which is generally used as an additive for alloy and stainless steel. It can enhance the strength, hardness, weldability and resistance of the alloy, as well as its high temperature strength and corrosion resistance. Abundant molybdenum boat resources. Like tungsten, molybdenum boat is a kind of refractory rare metal. Molybdenum boat has a melting point of 2620 ℃, and its strength is very high at room temperature and high temperature due to strong inter atomic binding force. It has small expansion coefficient, high conductivity and good thermal conductivity. It does not react with hydrochloric acid, hydrofluoric acid and alkali solution at room temperature, and is only soluble 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 boat and its alloys have a wide range of applications and good prospects in metallurgy, agriculture, electricity, chemical industry, environmental protection, aerospace and other important parts, and become an important raw material and irreplaceable strategic material in the national economy.
