Hello everyone, I am the youngest girl in the factory.
Today, let's talk about the treasure of 
the foundry industry-ductile iron castings.
Ductile iron castings are important casting metal materials 
developed in my country in the past 40 years.
Due to the small stress concentration caused by spheroidal graphite, 
the fracture effect on the matrix is also small, so the tensile strength, 
plasticity and toughness of ductile iron 
are higher than other cast irons.
Of course, ductile iron castings are not perfect.
 In addition to general casting defects, 
they also produce shrinkage porosity, slag inclusion, 
subcutaneous pores, poor spheroidization, and recession.
