Uses Of Molybdenum Alloys In The Aerospace And Steel Industry

Molybdænlegierungen are used owing to their high strength, mechanical stability and ductility. They find applications in high-temperature heating elements, extrusion grinding tools, glass melting electrodes, spray coatings, metal fabrication tools and aerospace components.

Applications of Molybdænlegierungen in the Aerospace Industry

Commercially, Molybdæn–copper alloys are used in the aerospace sector. They serve as non-ferrous alloys with Molybdæn as the matrix and include elements such as Titanium, Zirconium, Hafnium, Tungsten and Rare Earths.

These alloying elements provide solid-solution strengthening and maintain low-temperature plasticity. They also form a stable, dispersed carbide phase which improves the alloy strength and recrystallisation temperature.

Applications of Molybdænlegierungen in the Steel Industry

Molybdæn accounts for the largest proportion in the steel industry.

It is mainly used in the production of alloy steel, accounting for approximately 43% of the total Molybdæn consumption in the steel industry. It is also used in the production of stainless steel (approximately 23%), tool steel and high-speed steel (approximately 8%), cast iron and rollers (approximately 6%).

The majority of Molybdæn is employed directly in steel production or in cast iron following industrial Molybdæn oxide briquetting. A smaller fraction is first melted into ferromolybdæn and then used in steel production.

Molybdæn as an Alloying Element in Steel Confers the Following Advantages:

1. Enhanced strength and toughness of steel;
2. Improved corrosion resistance in acid–base solutions and liquid metals;
3. Increased wear resistance;
4. Better hardenability, weldability and heat resistance.

Hence, stainless steel with a Molybdæn content of 4% to 5% is frequently used in environments with significant erosion and corrosion, for example in ship fittings and chemical plants.
