Its properties are as follows: Due to the characteristics of the gray cast iron on so people use them a lot in the engineering industry, casting large ice machine, with high complexity, the details do not bear the big bend, but need good compression strength .
Cast iron is iron mixed with small amounts of silicon and carbon, and cast -- rather than formed -- in place. White cast iron, if cooled very slowly from melting, will become grey cast iron as the carbon atoms inside it bond together. The structure of the iron also allows it to dissipate energy very effectively, making it suitable for applications in which people want to dampen mechanical vibrations. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. The reasons behind its popularity are: ability to make complex structures and low cost. Grey Cast Iron is made by remelting pig iron. Gray iron castings are readily available in nearly all industrial areas and can be produced in foundries representing comparatively modest investments. The flake-like graphite structure gives rise to … Gray iron applications. You also cannot hammer or bend cast iron into a specific shape, which limits its potential for creative applications. Hence the casting molds serve longer. The graphite flakes can create areas of weakness in the … It is an alloy of Carbon and Iron. Common applications of cast iron. One area where grey iron is very popular is in the manufacturing of machine parts. Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Cast iron's composition and manufacturing techniques determine the properties of the finished product. It is an alloy of Carbon and Iron. Chilled Cast Iron.
Grey iron also conducts heat very well, which is one reason it is popular for cast iron pans, and it is electrically resistant. Instead, as the material breaks the graphite initiates numerous new cracks.
This type of iron is used for casting process in which grey cast iron layer is provided in inner surface and white cast iron layer is provided as outer surface. In grey cast iron, most of the carbon is present in the form of graphite flakes, which make the material softer, more machinable and less brittle than white cast iron. Chilled cast iron consists two layers of which one layer has white cast iron properties and other one has grey cast iron properties. Heat Treated Spheroidal Graphite Cast Iron Applications: agricultural, automotive machinery
Grey is the most versatile and widely used cast iron.
The presence of carbon leads to formation of graphite flakes that does not allow cracks to pass through, when the material breaks.
