FeMo55

FeMo is an iron alloy composed of molybdenum and iron, generally containing 50% to 60% of molybdenum, and is used as an alloy additive in steelmaking. Ferromolybdenum is an alloy of molybdenum and iron. Its main use is as an additive to molybdenum in steelmaking. The addition of molybdenum to the steel can make the steel have a uniform fine-grained structure, improve the hardenability of the steel, and help to eliminate temper brittleness, as well as alloys with special physical properties. The addition of molybdenum to cast iron increases its strength and wear resistance.

Specifications: Natural block, 10-100mm, or customized according to customer requirements.

APPLICATION

The role of molybdenum in steel can be summarized as improving hardenability, improving thermal strength, preventing temper brittleness, improving remanence and coercivity, and corrosion resistance in certain media, and preventing pitting corrosion. Due to the various beneficial effects of molybdenum in steel, it has been widely used in a series of steel grades such as structural steel, spring steel, bearing steel, tool steel, stainless acid-resistant steel, heat-resistant steel (also known as heat-strength steel), and magnetic steel.Molybdenum is very effective in improving strength and toughness in cast iron. When the addition amount is 0.25% to 1.25%, it can also form pearlite matrix structure for castings with medium and large sections. Commonly used in rolls and other wear-resistant castings.
