OEM / ODM Ductile Iron Sand Casting Parts – Ductile Iron Sand Casting Manufacturer

Short Description:

Ductile iron refers to cast iron in which the graphite is spherical 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. The spheroidization rate refers to the percentage of the total number of spherical graphite in a certain range to the total number of graphite. The spheroidization rate is an index to measure the spheroidization grade of nodular cast iron, and it is an important standard in ductile cast iron castings.

OEM / ODM Ductile Iron Sand Casting Parts – Ductile Iron Sand Casting Manufacturer Detail:

Cast Ductile Iron Sand Casting Manufacturer from China with Custom and CNC Machining Services.

Cast iron is an iron-carbon cast alloy with other elements that is made by remelting pig iron, scrap, and other additions. For differentiation from steel and cast steel, cast iron is defined as a cast alloy with a carbon content (min 2.03%) that ensures the solidification of the final phase with a eutectic transformation.

Depending on chemical specifications, cast irons can be non- alloyed or alloyed. The range of alloyed irons is much wider, and they contain either higher amounts of common components, such as silicon and manganese, or special additions, such as nickel, chromium, aluminum, molybdenum, tungsten, copper, vana- dium, titanium, plus others. Generally speaking, the cast iron could be divided into gray iron, ducitle iron (nodular iron), white cast iron, compacted graphite iron and malleable cast iron.
