Brinell hardness number - 207 - 320
Modulus of elasticity - 1*105 N/mm2
poisson's ratio - 0.23
modulus of rigidity - 0.350 * 105
What else can I help you with?
When carbon in cast iron is principally form of graphite the colour of the cast iron will be?
grey
What are the characteristics of spheroidal grey cast iron and how it is better than cast steel?
Cast Iron does not rust or corrode as steel can
What mean cast iron matrix?
The mean cast iron matrix refers to the microstructural arrangement of graphite and iron in cast iron, which significantly affects its mechanical properties. It typically consists of a network of ferrite or pearlite, embedded with graphite flakes or nodules, depending on the type of cast iron. The matrix influences characteristics such as strength, ductility, and wear resistance. Understanding the mean cast iron matrix helps in tailoring cast iron compositions for specific applications.
How silicon content affect microstucture and consequently mechanical propertise of cast iron?
because the cast iron is a ferrous metal
What are the properties of heat resistant cast iron?
It has austenitic matrix with very good heat and corrosion resistance properties upto 1500 F
What are the weaknesses of iron?
Pure iron has bad mechanical properties.
How is the cast iron welding rod made?
Cast iron welding rod is designed for the SMAW process which is built by flux and a filler metal that suits the base metal's chemical & mechanical properties.
What are the properties of cast irons?
Mechanical Properties of Ductile Iron. Ductile iron is characterized by having all of its graphite occur in microscopic spheroidsCast iron is formed by remelting pig iron, and is useful for a variety of engineering purposes.Properties and Uses of Iron. Iron is one of the three magnetic elements (the others are cobalt and nickel). Cast iron is very brittle (it cracks easily
What is the classification of cast iron?

What does SGI on a engine block mean?
Spheroidal Graphite (Cast) Iron. As the name implies, graphite is present in spheroidal form instead of flakes and compared with Grey Cast Iron it has higher mechanical strength, ductility and increased shock resistance.
What is the colour of iron after rusting?
As for the most of rough surfaces of cast iron, the color is grey. Such as normal grey cast iron and ductile iron. The ductile iron will be more white than grey cast iron. There are few types of vermicular cast iron, which are black. The white cast iron will show white color. So, cast iron has different color, such as grey, black, white according to different types. However, most of cast iron castings need surface coating, such as painting or electroplate, so they will show different colors than their own.
What is color of ductile iron?
Ductile iron typically has a dark grey color, similar to that of cast iron. It may also have a slight metallic sheen when freshly cast.
What are the uses of cast iron?
Cast iron mainly includes grey cast iron, ductile cast iron and malleable cast iron. As for ductile iron, it has very wide application, such as Pressure pipes and fittings, Automotive applications, Agriculture, road and construction applications, General engineering applications. As for the specific application of ductile iron, grey iron and malleable cast iron, please refer to the links below.

Is castability grey iron or ductile iron?
Castability refers to how easily a material can be shaped into a desired form using casting processes. Both grey iron and ductile iron have good castability, but grey iron is often favored for its excellent fluidity and ability to fill intricate molds. Ductile iron, while also castable, offers superior tensile strength and ductility, making it suitable for applications requiring enhanced mechanical properties. Ultimately, the choice between the two depends on the specific requirements of the casting application.
