Elimination and Neutralization of Boron in Ductile Irons

levels of boron have been reported to act as carbide stabilizers and promote pearlite while recently others have reported just the opposite effect. Boron levels in the range of 0.0011% to 0.0020% (11 to 20 ppm’s) reduce pearlite levels in pearlitic ductile irons and reduce Brinell hardness levels (BHN). Large quantities of pearlite
