The Effect of Molybdenum on the steelmaking

The Effect of Molybdenum on the Mechanical Properties of Steel
1. Molybdenum has a Solid solution strengthening effect on ferrite, and also improves the stability of carbide, thus improving the strength of steel.
2. Molybdenum plays a beneficial role in improving the ductility, toughness, and wear resistance of steel.
3. Due to the increase in softening and recovery temperature and recrystallization temperature after deformation strengthening, as well as the strong increase in the transformation resistance of ferrite, it effectively inhibits the aggregation of cementite at 450-600 ℃, promotes the precipitation of special carbides, and thus becomes the most effective alloying element for improving the thermal strength of steel,
The Effect of Molybdenum on the Physical, Chemical, and Technological Properties of Steel
1. In the magnetic steel containing 1.5% carbon, 2% -3% molybdenum improves the residual magnetic induction and Coercivity.
2. Molybdenum can passivate the surface of steel in both reducing acids and strong oxidizing solutions, so it can generally improve the corrosion resistance of steel and prevent pitting corrosion of steel in oxide solutions.
When the aluminum content is high (>3%), the oxidation resistance of steel deteriorates.
4. Steel containing no more than 8% molybdenum can still be forged and rolled, but when the content is high, the deformation resistance of steel to Hot working will increase.
