Ferro Silicon Rare-Earth

Chemical Formula Available Form Description of the Product
RE – 8-10%, 30-33%, 30-35%, Si – 35-55%, Fe- balance Lumps, Granules, Powder It is used in steel industry to modify the shape of nonmetallic inclusions into one that will not harm mechanical properties – so called “inclusion shape control”. Sulfide, oxide and silicate inclusions can be soft enough at hot working temperatures to deform into long stringers oriented parallel to the hot rolling direction. Their presence is especially harmful to transverse ductility and impact strength since they act as infinitely sharp internal notches, or crack initiators.
