DUCTILE IRON PIPE - McWane
pe.mcwane.comDuctile Iron also differs from Gray Iron in that its graphite form is spheroidal, or nodular, instead of the flake form found in Gray Iron. This change in graphite form is accomplished by adding an inoculant, usually magnesium, to molten iron of appropriate composition during manufacture. Due to its spheroidal graphite form, Ductile Iron has ...

nickelinstitute.orgNi-Resist Austenitic Cast Iron Alloys There are two families of Ni-Resist austenitic cast irons. These are the standard or flake graphite alloys and the ductile or spheroidal graphite alloys. As time passes, the spheroidal grades, because of higher strength, ductility and elevated temperature properties, are becoming more prominent.

Heat Treatment of Cast Irons - Heat Treat Doctor.com
www.heat-treat-doctor.comNodular iron, also known as ductile iron or spheroidal graphite iron, is cast iron in which the graphite is present as tiny balls, or spherulites, instead of graphite flakes (as in gray iron), or compacted aggregates (as in malleable iron). The nodular irons typi-cally contain from 3.2-4.1% C, 1.8-2.8% Si and up to 0.80% Mn as major constituents.
