Product Description
Ferromolybdenum is an iron-molybdenum master alloy widely used as a molybdenum additive in steelmaking, casting, and alloy material production. Our company specializes in the international trade of ferromolybdenum products, strictly adhering to GB/T 3649-2008 national standard, and can provide customized specifications according to customer requirements.
Ferromolybdenum is an alloy composed primarily of molybdenum and iron, containing 55% to 75% molybdenum by weight. It is classified under CAS 12382-30-8. The product appears as silver-gray to dark gray metallic lumps. Ferromolybdenum exhibits good corrosion resistance and oxidation resistance.
The main grades include FeMo70, FeMo60-A, FeMo60-B, FeMo60-C, FeMo55-A, and FeMo55-B, and can also be customized according to customer requirements.
According to GB/T 3649-2008, ferromolybdenum is divided into six grades based on molybdenum content and impurity levels. The chemical composition shall comply with the following table:
| Grade | Chemical Composition (mass fraction %) | |||||||
| Mo | C (≤) | S (≤) | P (≤) | Si (≤) | Cu (≤) | Sb (≤) | Sn (≤) | |
| FeMo70 | 65.0–70.0 | 0.10 | 0.08 | 0.05 | 2.0 | 0.50 | — | — |
| FeMo60-A | 60.0–65.0 | 0.10 | 0.08 | 0.04 | 1.0 | 0.50 | 0.04 | 0.04 |
| FeMo60-B | 60.0–65.0 | 0.10 | 0.10 | 0.05 | 1.5 | 0.50 | 0.06 | 0.05 |
| FeMo60-C | 60.0–65.0 | 0.15 | 0.15 | 0.05 | 2.0 | 1.00 | 0.08 | 0.08 |
| FeMo55-A | 55.0–60.0 | 0.15 | 0.10 | 0.08 | 1.0 | 0.50 | 0.06 | 0.05 |
| FeMo55-B | 55.0–60.0 | 0.20 | 0.15 | 0.10 | 1.5 | 0.50 | 0.08 | 0.08 |
Note: The above data is based on GB/T 3649-2008. Specific indicators can be adjusted according to customer requirements. For FeMo70, the molybdenum content is typically specified as 65–75% in some references.
| Application Area | Specific Uses |
| Steelmaking | Used as a molybdenum addition agent and alloying element; improves steel properties, creates uniform fine-grained microstructure, lowers the eutectoid decomposition temperature, and expands the quenching and tempering temperature range |
| Stainless Steel | Widely used in the production of stainless steel, heat-resistant steel, and acid-resistant steel |
| Tool Steel & High-Speed Steel | Molybdenum can partially replace tungsten in high-speed steel; improves hardenability and eliminates temper brittleness in nickel-chromium steel |
| Cast Iron | Improves casting structure, increases strength, and enhances the high-temperature performance and wear resistance of gray cast iron |
| Special Alloys | Applied in the production of special alloys with specific physical properties |
