Alloy steel, stainless steel, tool steel and cast iron are the main application fields of molybdenum, and their production capacity determines the demand for molybdenum. So what are the roles of molybdenum in steel? Here is a brief introduction of sodium molybdate
1. A kind of hard martensite structure is obtained by reducing the cooling rate to an appropriate value, which improves the strength, hardness and toughness of large section components;
2. Reduce temper brittleness;
3. Hydrogen embrittlement resistance;
4. Resistance to sulfide induced stress cracking;
5. Sodium molybdate improves high temperature strength;
6. Improve corrosion resistance of stainless steel, especially chloride pitting;
7. Sodium molybdate improves the weldability of high strength low alloy steel.
