Product Description
Grey Iron and Ductile Iron Sand Shell Mold Casting
Product description :
Ductile iron is a relatively new form of castings, where magnesium is added to force the nodulation of
carbon. Ductile iron has a larger carbon content in the form of nodules followed by a primarily ferrite
matrix. Ductile iron grades generally trade off the strength to the percent elongation. The purity of the
steel/iron that is used to make the ductile iron can have a large impact on the quality of the casting.
Generally ductile iron castings have test bars that are poured with each heat, and these can be used to
identify the casting quality. Control of the melt is extremely important, as under-cooling can cause
various negative formations to occur including dendritic and kisch type forms.
Grey iron castings are an older, cheaper form of casting. A foundry that pours ductile iron may also
pour various grades of Grey iron. Metallurgical composition control is less severe for grey irons.
However, the cost of grey iron is lower than that of ductile iron.
Testing equipment
Testing equipment: tensile testing machine, nodularity check microscope, spark chemistry
measurement, brinnel hardness tester, izod impact testing.
Machinery List: furnace capacity, load tonnage
