Machining Ductile Iron
The gray iron of cast iron is obtained by spheroidizing treatment, and the precipitated graphite is spherical, which is referred to as ductile iron. All or most of the carbon is present in the free state of spheroidal graphite, and the fracture is silvery gray. It has higher strength, better toughness and plasticity than ordinary gray cast iron. Its grade is indicated by two digits after "QT", for example: QT45-5 (the first set of numbers indicates the lowest tensile strength and the second set of numbers indicates the lowest elongation). Used in the manufacture of internal combustion engines, auto parts and agricultural machinery.

(1) Annealing - the purpose is to obtain ferrite matrix structure and eliminate casting stress;
(2) normalizing - the purpose is to obtain P or P + F matrix, refine the structure, improve strength and wear resistance;
(3) tempering - in order to obtain good comprehensive mechanical properties;
(4) Austempering - in order to obtain the ductile iron of the B under the base.
