What is GGG40?
What is GGG40?
GGG40 is the most commonly used nodular cast iron alloy and has a predominantly ferritic structure. This cast iron offers excellent machinability combined with good impact resistance, high electrical conductivity, good elongation properties and magnetic permeability. The material cannot be welded.

What GJS 400?
EN-GJS-400 ductile iron, also called as nodular iron, is a very good and common cast iron. It has good tensile strength and yield strength, and the largest elongation compared with other ductile iron grades. Moreover, it has the best impact property, casting and machining functions.
What are the grades of cast iron?
The 4 Types of Cast Iron
- #1) Gray Cast Iron. The most common type, gray cast iron features a graphite microstructure consisting of many small fractures.
- #2) White Cast Iron. While not as common as gray cast iron, white cast iron is another type worth mentioning.
- #3) Ductile Cast Iron.
- #4) Malleable Cast Iron.
What is the difference between SG iron and cast iron?
The difference between traditional cast iron and modern-day ductile iron is the shape of the graphite. While cast iron has small flakes of graphite, ductile iron contains spherical graphite nodules. Because of the spherical shape of the graphite, ductile iron is often called spheroidal iron or nodular cast iron.
What is the density of ductile iron?
An Introduction to Ductile Iron
| Property | Minimum Value (S.I.) | Maximum Value (S.I.) |
|---|---|---|
| Density | 7.05 | 7.25 |
| Energy Content | 60 | 72 |
| Bulk Modulus | 119 | 137 |
| Compressive Strength | 229 | 799 |
What is the Rockwell hardness of cast iron?
40.0 – 800
| Physical Properties | Metric | English |
|---|---|---|
| Hardness, Rockwell B | 40.0 – 800 | 40.0 – 800 |
| Hardness, Rockwell C | 11.4 – 65.0 | 11.4 – 65.0 |
| Hardness, Vickers | 151 – 871 | 151 – 871 |
| Tensile Strength, Ultimate | 90.0 – 1650 MPa | 13100 – 240000 psi |
How do you make cast iron ductile?
Ductile iron casting refers to a process in which magnesium / cerium (as an alloy of magnesium / cerium) is added to cast iron. It reacts with the sulfur and oxygen in the molten iron and changes the way the graphite is formed.
Is SG iron malleable?
As the name Ductile Iron suggests this grade of Cast Iron has a degree of ductility. The main characteristic of this material is the structure of the graphite. In SG Cast Iron the graphite is in the form of spherical nodules (hence the name Spheroidal Graphite) rather than flakes as in Grey Iron.
Is ductile iron and SG Iron the same?
SG Iron is also known as Ductile Cast Iron, Nodular Cast Iron, Spheroidal Graphite Iron and Spherulitic Cast Iron. This grade of Iron was developed over 60 years ago and in the USA. As the name Ductile Iron suggests this grade of Cast Iron has a degree of ductility.
