Cast iron is a ferrous alloy which has more than 2% carbon in it. Though it can have any percentage of carbon between 2 Following are some important types of it. Grey. Ductile. Compacted graphite. White cast iron. Carbon is present here in the form of Iron carbide (Fe3C). Its properties are.

Ductile irons are therefore a family of alloys, which combine the principle advantages of gray iron (low melting point, good fluidity and castability, excellent machinability, and good wear resistance) with the engineering advantages of steel ( high strength, toughness, ductility, hot workability and hardenability)
Since there are limitation of the mechanical properties of gray cast iron such as hardness, tensile strength and others so, the white cast iron is needed. The mechanical properties of white cast iron is better than grey cast iron in order to produce something that need strength and ability to against the large force exerted on it.
graphite.It is the most common cast iron and the most widely used cast material based on weight. Gray cast iron with its evenly distributed lamellar graphite dampens sound waves and is corrosion and wear resistant. The areas of application for gray cast iron products extend from heavy components for frames,
Cast iron possesses the highest strength, hardness, resistance to wear and heat treat response for an unalloyed gray iron. It is widely used for bearing and bushing applications in the hydraulics industry. Tensile strength runs from 27,000-40,000 psi depending on section size.

Tensile strength (UTS) is the maximum tensile load a material can withstand prior to fracture. Learn more. 190 - 300 MPa at 20 °C. Show Grey Cast Iron materials with Tensile strength of 190 - 300 MPa at 20 °C.
Sep 12, 2018 · Gray iron consists of graphite flakes in a metallic matrix. When fractured, it is grayish in colour – hence the name (specifically, a fracture will follow along the graphite flakes which are gray). The low cost of production and attractive properties make gray iron one of the most commonly used ferrous alloys.

  • We cast ductile iron, ADI, CADI, Ni-Resist, Ni-Hard, and compacted graphite, also gray iron and many other metals. CSP also develops custom and proprietary alloys for steel mill wear parts, and we have the capability to meet specific requirements for micro structure and other physical properties
  • Grey Cast Iron (Gray iron) is so called because of the colour of the fracture face. It contains 1.5-4.3% carbon and 0.3-5% silicon plus manganese, sulphur and phosphorus. It is brittle with low tensile strength, but is easy to cast.
  • Material properties are physical properties of materials which shall be assesed as a selection criteria for a given application. Some of the material properties, which directly affect the choice of material, are yield and tensile strength, ductility, poisson's ratio, density, modulus of elasticity, coefficient of thermal...
  • Malleable cast iron is white cast iron that has been annealed. Through an annealing heat treatment, the brittle structure as first cast is transformed into Properties of Malleable Cast Iron - ASTM A220. Material properties are intensive properties, that means they are independent of the amount of mass...
  • Grey Cast Iron is made by remelting pig iron. It is an alloy of Carbon and Iron. Small amounts of Silicon, Phosphorus, Manganese and Sulfur are also present in it. The reasons behind its popularity are: ability to make complex structures and low cost. In addition, the excellent properties of Grey Cast...

Grey Cast Iron Grey Cast Iron is the most common general purpose cast iron. Manufacture is straightforward and it can easily be cast into intricate shapes. The graphite is present in large flat flakes within the crystal structure of the iron. These flakes behave like microscopic fault lines allowing cracks...

However, the cast iron made in foundries is a mixture of many elements. Most of them have a significant effect on the properties of the iron. Atoms of the element iron make up about 95% of all of the atoms in cast iron. The chart below gives typical percentages of some of the other elements found in gray and ductile iron.
