CRITICAL WARNINGS
1. Molybdenum Content: Ferro molybdenum typically contains 60-75% molybdenum. The exact composition should be verified before use for precise alloying calculations.
2. Steel Hardening: FeMo significantly increases the hardness, strength, and heat resistance of steel. Ideal for producing stainless steel, tool steel, and high-strength low-alloy (HSLA) steel.
3. Corrosion Resistance: Molybdenum enhances steel's resistance to pitting and crevice corrosion, especially in chloride environments (marine, chemical processing).
4. Heat Resistance: Steels containing molybdenum maintain mechanical properties at elevated temperatures. Essential for high-temperature applications (turbines, boilers, furnaces).
5. Addition Timing: FeMo should be added to molten steel during the later stages of steelmaking (ladle metallurgy). Proper addition ensures optimal distribution and recovery.
6. Recovery Rate: Molybdenum recovery in steelmaking is typically 90-98% when FeMo is properly added. Consider recovery rate in alloy calculations.
7. Dust Hazard: FeMo dust can cause respiratory irritation. Use dust suppression measures during handling, crushing, and screening operations.
8. Welding Fumes: Welding or melting FeMo-containing materials may produce toxic molybdenum compound fumes. Use proper fume extraction and ventilation.
9. Storage: Store in a dry environment to prevent moisture absorption and potential caking. Protect from acids and oxidizing agents.
10. Quality Control: Verify chemical composition (Mo, Si, C, S, P) for each batch. Impurities can affect steel quality.
11. Recycling: Ferro molybdenum and molybdenum-containing scrap are 100% recyclable with high commercial value.
12. Critical Raw Material: Molybdenum is listed as a critical raw material by the EU and other regions. Supply chain considerations are important.
