- Sep 05, 2019-

Ductile iron. The gray cast iron hot metal is obtained by spheroidizing treatment, and the precipitated graphite is spherical, which is referred to as ductile iron. It is obtained by adding a certain amount of spheroidizing agent and inkizing agent to the molten iron to promote the crystallization of the spherical graphite. Compared with steel, it is used for the manufacture of internal combustion engines, auto parts and agricultural machinery, in addition to plasticity and toughness.
