Ductile Iron - Dy-Kast

Ductile Iron What Ductile Iron Is Ductile iron is a family of cast graphitic irons which possess high strength, ductility and resistance to shock. Annealed cast ductile iron can be bent, twisted or deformed without fracturing. Its strength, toughness and ductility duplicate many grades of steel and far exceed those of standard gray irons. Yet it

Ductile Iron Metal Casting Resources

Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted, or deformed without fracturing. Its mechanical properties are similar to steel, and far exceed those of standard cast irons. Ductile iron castings are solid metal objects that result from molten ductile iron being poured into voids in a mold. The ductile iron ...

Graphite Formation and Dissolution in Ductile

Sep 07, 2018  Sep 07, 2018  Graphite formation in the solid state is both in ductile cast irons and in steels strongly promoted by high silicon contents above 3 wt.% Si. The matrix microstructure in austempered ductile iron can be further refined by secondary graphite if the austenitization, quench, and isothermal transformation into ausferrite are preceded by an austenitization at a slightly higher

Metallography of cast iron insight Struers

The term cast iron refers to iron-carbon-silicon alloys that contain 2.5-4 % carbon and usually 1-3 % silicon. In grey irons, the carbon is present as graphite; in white cast iron it is present in the form of iron carbide and alloy carbides. Cast iron has good castability and machinability, as well as moderate mechanical properties.

Manufacturers of cast iron from India and elsewhere use the inoculation for industrial quality castings. Without any other alloy additions, an extremely slow cooling rate would result in the precipitation of carbon as graphite, which reduces its quality.
