Graphite Floatation In Ductile Irons Gray cast iron CHUNK GRAPHITE DEFECTS IN DUCTILE IRON by James D Mullins Sorelmetal Technical Services One of the biggest problems that RIT Technical Services metallurgists come across when we visit foundries is chunk graphite Ductile iron is an alloy of iron rich with graphite whereas cast iron is an alloy of iron that we can readily cast in a mould When considering the composition of each iron alloy the ductile iron contains iron carbon silicon manganese magnesium etc along with copper or tin while the cast iron contains iron carbon silicon manganese along with trace amounts of sulfur and phosphorous

Is graphite ductile

By adding inoculant to the liquid iron just before casting undercooling can be minimized Inoculation is a means of controlling the structure and properties of cast irons by increasing the number of nucleation sites available for the growth of graphite flakes in grey irons or graphite nodules in ductile irons While there is no large difference when it comes to tensile strength ductile iron has the greater yield strength (40 ksi) Cast steel on the other hand can only reach 36 ksi yield strength Ductile Iron (ASTM A536) vs Cast Steel (ASTM A27) As the strength of ductile iron increases ductility decreases
