Ferro Selenium

Chemical Formula Available Form Description of the Product
Se – 50% ,Fe -50% Dia = 9mm Cored Wire,Powder It improves the machinability of steels. Also helps to reduce the rate of nitrogen absorption in liquid steel, and steels treated in this fashion will have better cold forming properties. High alloy steel castings inoculated with 0.02% Selenium will show less pinhole porosity, even at hydrogen concentrations of 8 to 11 ppm. 0.05 -0.1% Selenium reduce rate of nitrogen absorption in liquid steel, giving better cold forming properties.
