Ductile iron profiles effectively improve the mechanical properties of cast iron, in particular the plasticity and toughness, resulting in higher strength than carbon steel.
The nodular cast iron profile is obtained by spheroidizing the gray cast iron hot water, and the precipitated graphite is spherical, referred to as ductile iron. It has higher strength, better toughness and plasticity than ordinary gray cast iron, and is used for manufacturing internal combustion engines, auto parts and Agricultural machinery and so on.
Ductile iron profiles, with their excellent properties, can sometimes replace expensive cast steel and forged steel in use, and are widely used in the mechanical manufacturing industry.
