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