Molybdenum And Its Uses
Molybdenum ("mo-lib-den-um") (Mo, periodic table element #42) is used principally as an alloying agent in steel, cast iron, and superalloys to enhance hardenability, strength, toughness, and wear and corrosion resistance. The versatility of molybdenum in enhancing a variety of alloy properties has ensured it a significant role in contemporary industrial technology, which increasingly requires materials that are serviceable under high stress, expanded temperature ranges, and highly corrosive environments. Moreover, molybdenum finds significant usage as a refractory metal in numerous chemical applications, including catalysts, lubricants, and pigments. Few of molybdenum's uses have acceptable substitutions.

Initial applications of molybdenum were as a cost-effective replacement for tungsten in specialty steels. (The density of molybdenum is about half that of tungsten, so it only takes 1% molybdenum to equal roughly 2% tungsten.)

Molybdenum has found its way into a variety of alloys used in severe operating environments. Alloys containing molybdenum are used in:

- Pipeline steel
- Automotive parts
- Aircraft engines
- Mining equipment
- Critical components in nuclear power plants
- Pollution control equipment
- Architectural applications
- High-speed drills, cutters, and saw blades
- Power plant condensers
- Chemical process equipment

But molybdenum's unique properties make it ideal for many other applications beyond alloys. Molybdenum is also used in chemical applications such as:

- Catalysts
- Chemical applications
- Pigments
- Corrosion inhibitors
- Smoke suppressants
- Lubricants
