Properties of ductile cast iron pipe

Ductile cast iron is a kind of alloy of iron, carbon and silicon, in which graphite exists in the type of spherical, generally the size of graphite is 6-7 class, and spheriodization grade of the pipe should be controlled 1-3 class ( spheriodization rate is not below 80% ). Thus after spheriodization, ductile cast iron pipe possesses the nature of iron as well as the characteristics of steel, After annealing, its microstructure contains of iron ferrite and a little pearlite possessing excellent mechanical properties.
