Molybdenum

 

 

Strength, toughness and wear resistance

Molybdenum, commonly referred to as Moly, is one of the world’s most important natural resources. There is a growing global demand for this versatile element due to its diverse application opportunities.

Diverse Applications

Metal Products

Molybdenum metal and alloys are used in a number of important end products including lamp applications, glass melting electrodes and electronic devices. The characteristics of molybdenum metal powders are determined not only by the process conditions during reduction, but also by the physical and chemical properties of the starting materials.

Lubricants

The naturally occurring form of molybdenum (MoS2) is an important solid lubricant used primarily for reduction of wear and friction, and maintains good lubricating performance in tough conditions. Molybdenum complexes, soluble in petroleum oils and other organic solvents, are finding increased use as antiwear and extreme pressure additives as well as friction modifiers in lubricating oils, greases and coatings.

Corrosion Inhibition

Molybdate, usually in the form of Sodium Molybdate, is used as an anodic corrosion inhibitor in aqueous systems, such as cooling water treatments and automobile anti-freeze/coolant products. It is effective in inhibiting corrosion of steel, cast iron, aluminum, copper, brass, cadmium and solder, and is typically used with other corrosion inhibitors.

Stainless Steel

Molybdenum is primarily used to improve the corrosion resistance of stainless steel in more demanding applications, such as chemical processing plants or in marine applications. The addition of molybdenum increases the pitting and crevice corrosion resistance of stainless steels in chloride containing solutions.

Allot Steel & Iron

To increase hardness and wear resistance over a broad temperature, molybdenum is added to tool- and high-speed steel. It increases the strength and hardness of cast iron, as well as increases elevated temperature strength and creep resistance. In high-strength, low alloy steels (HSLA) molybdenum improves strength and weldability.

Nickle Based Alloys

Molybdenum is an important alloying element in high performance nickel base alloys. The corrosion-resistant nickel base alloys find extensive use in the chemical processing, pharmaceutical, oil and gas, petrochemical, and pollutioncontrol industries.
