Description
Ductile Iron Casting
Ductile iron refers to cast iron in which the graphite is spheroidal after the molten iron is treated with a spheroidizing agent. That is why the ductile cast iron is also called spheroidal graphite cast iron or nodular cast iron. Inside the ductile cast iron by electron microsope, the shape of spheroidal graphite is approximately spherical, and its interior is radial shape, and it has obvious polarization effect.
We produce custom ductile iron castings mainly by sand casting and shell mold casting processes. The high accuracy of the ductile castings is significantly reduced the possiblities of mechanical machining operations to a minimum level. Ductile iron casting as per customer's drawings is our key portion of casting service but not our only service.
Nodular cast iron obtains nodular graphite through spheroidization and inoculation treatment, which effectively improves the mechanical properties of the cast iron, especially the plasticity and toughness, so as to obtain higher strength than carbon steel.
Ductile iron is not a single material but is part of a group of materials which can be produced to have a wide range of properties through control of the microstructure. The common defining characteristic of this group of materials is the shape of the graphite. In ductile irons, the graphite is in the form of nodules rather than flakes as it is in grey iron.
