cast iron alloy
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 is gjs400?
EN-GJS-400-18 and EN-GJS-400-15 are SG iron grades containing graphite nodules or spheres, Spheroidal Graphite. The rounded graphite nodules produces a more ductile cast iron that inhibits the formation of cracks. SG iron has a greater fatigue and impact resistance compared to grey 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.
Is 1865 a chemical composition?
Spheroidal or nodular graphite cast iron or ductile iron is a casting alloy of iron and carbon, carbon being present in the spheroidal form. Graphite flakes in cast iron act as discontinuities in the matrix and thus lower its mechanical proper- ties. The sharp corners of the flakes also act as stress raisers.
What is en Gjs?
EN-GJS-500-7 is an SG iron grade containing graphite nodules or spheres, Spheroidal Graphite. The rounded graphite nodules produces a more ductile cast iron that inhibits the formation of cracks. SG iron such as EN-GJS-500-7 has a greater fatigue and impact resistance compared to grey iron.
What are the three types 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 a chemical property of iron?
A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust (Figure 3.2. 2). The more general term for rusting and other similar processes is corrosion.
What is SG steel?
SG Steel is a steel and metal products procurement, supply, processing and fabricating company who serves numerous industries such as construction, energy, engineering, and more. Products include plates, beams, and industrial bars.
What are the characteristics of ggg40?
Characteristics of 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 is ggg40 cast iron?
Cast iron GGG40 is a low grade of ductile iron. Our foundry has produced this material for many years, and herein, we introduce its mechanical and chemical properties and some iron castings made by this material grade.
Can ggg40 be welded?
The material cannot be welded. Because GGG40 is extremely tough, it is suitable for components that are subjected to large forces; e.g. levers, chain links, housings, brake shoes and connecting rods. Notch impact strength at 20 °C. 0.02 max.
What is the equivalent of grade ggg40 in other countries?
