◉ Product Description

Ferromolybdenum (Ferro Molybdenum) Product Introduction

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.

1. Product Introduction

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.

2. Product Grades and Chemical Composition

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:

GradeChemical Composition (mass fraction %)







MoC (≤)S (≤)P (≤)Si (≤)Cu (≤)Sb (≤)Sn (≤)
FeMo7065.0–70.00.100.080.052.00.50——
FeMo60-A60.0–65.00.100.080.041.00.500.040.04
FeMo60-B60.0–65.00.100.100.051.50.500.060.05
FeMo60-C60.0–65.00.150.150.052.01.000.080.08
FeMo55-A55.0–60.00.150.100.081.00.500.060.05
FeMo55-B55.0–60.00.200.150.101.50.500.080.08

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.

3. Main Applications

Application AreaSpecific Uses
SteelmakingUsed 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 SteelWidely used in the production of stainless steel, heat-resistant steel, and acid-resistant steel
Tool Steel & High-Speed SteelMolybdenum can partially replace tungsten in high-speed steel; improves hardenability and eliminates temper brittleness in nickel-chromium steel
Cast IronImproves casting structure, increases strength, and enhances the high-temperature performance and wear resistance of gray cast iron
Special AlloysApplied in the production of special alloys with specific physical properties
