Ferromolybdenum (FeMo), is an alloy consisting of iron and molybdenum.  It is an extremely versatile alloy used primarily in high-strength low alloys and stainless steels. It has numerous beneficial properties and can be used even in cast irons, some high-speed tool steels, and superalloy applications. Adding ferromolybdenum to a material helps to improve weldability, corrosion and wear resistance as well to increase ferrite strength.

For a complete listing of ferromolybdenum specifications, see ASTM A132.


Sampling Services for Ferromolybdenum

Contact Us Today

McCreath Laboratories will send trained, experienced technicians to take a represented sample for you.  Whether in bulk or containers, our technicians have the training, tools and experience to collect a representative sample, ensuring that all subsequent laboratory testing is accurate and reliable.  With our mobile crushing units, ferromolybdenum in lump form can be partially processed on site per the ISO and ASTM standards, increasing efficiency and reducing the amount of material taken off-site.

Work With The Experts

McCreath Laboratories will employ both classical and advanced in-house techniques in the analysis of ferromolybdenum.  The techniques have been verified through the use of certified reference materials and some are adopted directly from ASTM or ISO standards.  A typical ferromolybdenum analysis would be done as follows:
