Ferro Molybdenum

Ferro molybdenum (FeMo) is an important alloy composed primarily of iron and molybdenum, typically containing 60–75% molybdenum by weight. It is a critical additive in the steel and alloy industries, where it enhances mechanical properties such as strength, hardness, corrosion resistance, and weldability. The addition of molybdenum to steel significantly improves its performance under high temperature and pressure conditions, making ferro molybdenum indispensable in various high-stress applications.

The production of ferro molybdenum generally involves the reduction of molybdenum oxide (MoO₃) using ferrosilicon in the presence of iron. This process is carried out in an electric arc furnace or blast furnace. The resultant alloy is then cooled, crushed, and screened into granules or powder, depending on the customer’s requirements. The exact composition and form of ferro molybdenum can be customised for specific industrial applications.

One of the primary uses of ferro molybdenum is in the manufacture of alloys and stainless steels. Molybdenum enhances the hardenability and toughness of steel, allowing it to maintain its strength at elevated temperatures. This makes ferro molybdenum a vital material in producing high-speed tool steels, automotive parts, gas pipelines, and components for the aerospace and defence sectors. It is also crucial in the oil and gas industry, particularly for drill bits and equipment subjected to extreme operational conditions.

Beyond steelmaking, ferro molybdenum is used in the production of superalloys, which are essential for turbines and jet engines. Its presence in these alloys ensures resistance to heat, wear, and corrosion—qualities that are critical for performance and safety in demanding environments.
