S G Iron Rolls, Spheroidal Graphite Iron Rolls, Acicular

Acicular Spheroidal Graphite Rolls: Acicular Spheroidal Graphite Rolls also have a thick layer of cast iron with nodular graphite, here, the name of such roll is based on the fact that the material consists of nodular graphite and carbides in a pearlitic - bainitic matrix, the carbide content is considerably higher in the harder grades than the softer ones.

Wear analysis of spherical graphite cast iron using pin

Abstract Cast iron is widely used due to low price, good machining and good damping capability. However, it has huge friction. In certain automotive components such as cylindrical liner, cast iron is used. The biggest challenge in cylinder liner is obtaining lower friction

AS 1831 for Ductile Cast Iron

Ductile cast iron is also known as spheroidal graphite cast iron, and less commonly as nodular iron. It is a kind of cast material, iron and carbon-based, the carbon being present mainly in the form of spheroidal graphite particles. The following three tables have

Ductile Cast Iron: Process, Composition, Differences and

Ductile cast iron (also called as spheroidal graphite cast iron or nodular cast iron) has been widely used as a main industrial material in place of high-grade cast iron. While most varieties of cast iron are comparatively brittle, ductile iron castings are much more ductile due to the inclusion of nodular graphite.

Reclassification of Spheroidal Graphite Ductile Cast Irons Grades

Low and normal silicon spheroidal graphite cast iron grades are the most suited for obtaining sound castings. High silicon grades are more prone to formation of porosity and/or chunky graphite. Process FP Pearlite Promoters Added to Modify the F–P Content

Ductile iron

Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.

Grey cast iron and ductile iron Casting

It is the most widely used cast iron, and its output accounts for more than 80% of the total output of cast iron. Ductile iron Casting is obtained by spheroidizing and inoculation to obtain spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thereby obtaining higher strength than carbon steel.

Cast Irons: Composition and Properties

When this cast iron is heated above the critical temperature, the austenite forms and in a short time, becomes saturated with carbon that is dissolved from graphite. The microstructure of the iron at a temperature slightly greater than T 2 shall have graphite and austenite of composition point C 1 as illustrated in Fig. 15.14.

Spheroidal Graphite (S.G) Iron

2021/2/15Spheroidal Graphite (S.G) Iron is the name given to that cast –iron, where the graphite is present in the matrix in the form of spheroid or globules or nodules. Hence it is also called as Nodular Iron and because of its exceptionally high ductility (with elongation some times as high as 22%) is also referred to as ductile iron.

Compacted Graphite Iron: Part Two :: Total Materia Article

Compacted graphite iron (CGI) along with lamellar graphite iron and spheroidal graphite iron define the three main classes of cast iron according to morphology. An important measure for assessing the application of CGI is the machinability levels and through specific studies it was concluded that CGI is much more difficult to machine than standard grey cast irons.
