Notes:
Molybdenum (Mo) is the primary alloying element.
Iron (Fe) forms the balance of the material.
The carbon, silicon, sulfur, and phosphorus contents are typically low to maintain high quality and desirable alloy characteristics.
The percentages mentioned above are typically the minimum content of Molybdenum, with the rest being iron and a very small amount of other elements.
Ferromolybdenum(FeMo 70)
FeMo 70 refers to a ferroalloy consisting of primarily iron (Fe) and molybdenum (Mo), with the molybdenum content being approximately 70% by weight. This specific composition of FeMo 70 is used primarily in the steel industry as an alloying agent to impart desirable properties to steel and other alloys.
Composition
-
Molybdenum (Mo): Around 70% by weight.
- Iron (Fe): The remainder, typically making up about 30%, although this can vary slightly based on the manufacturing process.
Production Process
- FeMo 70 is produced by reducing molybdenum oxide (MoO₃) with iron at high temperatures in a furnace, or by using hydrogen reduction.
- The alloy is typically produced in the form of small lumps or a fine powder, which is then used in the alloying process for steel or other metals.
Properties
- High Molybdenum Content: FeMo 70 has a high molybdenum content, which provides significant benefits to steel in terms of strength, hardness, and high-temperature performance.
- Improved Creep Resistance: Molybdenum significantly improves the steel's resistance to creep, which is the tendency of a material to deform permanently under the influence of stress and temperature over time.
- Corrosion Resistance: Molybdenum enhances resistance to corrosion, especially in harsh environments like acidic or saline conditions, making it valuable in industries where corrosion resistance is a priority.
- High-Temperature Strength: The presence of molybdenum helps maintain the strength and structural integrity of steel at elevated temperatures, which is crucial in many industrial applications.
- Tensile Strength: Molybdenum increases the tensile strength of steel, which makes it ideal for high-stress applications.

Benefits of FeMo 70 in Steel
- Heat Resistance: It improves the steel's ability to withstand high temperatures without losing strength, making it valuable in heat exchangers, turbines, and other high-temperature equipment.
- Wear Resistance: Molybdenum in FeMo 70 enhances wear resistance, particularly under high-stress conditions.
- Enhanced Hardness and Strength: It significantly increases the hardness and tensile strength of steel, which is essential in demanding industrial applications.
summary
FeMo 70 is a high-molybdenum ferroalloy, containing approximately 70% molybdenum, and is primarily used to alloy steel and other metals. Its high molybdenum content provides excellent corrosion resistance, high-temperature strength, and wear resistance, making it particularly valuable in industries such as aerospace, power generation, automotive, and steelmaking. FeMo 70 is crucial in producing steels with superior properties that can withstand extreme stress, temperature, and corrosive environments.
