Difference Between Grey & White Cast Iron | Sciencing

White cast iron, if cooled very slowly from melting, will become grey cast iron as the carbon atoms inside it bond together. Grey cast iron, by contrast, will keep its form if cooled slowly, but will become white cast iron if cooled very fast.

The difference between gray cast iron and white cast iron

Dec 16, 2019 · As we all know, there are several typical types of cast iron like grey cast iron, white cast iron, and ductile cast iron according to the composition of carbon and silicon. Most or all carbon in cast iron exists as flake graphite in free state. Gray cast iron is the most common and widely used cast iron.

Difference Between Grey Cast Iron and White Cast Iron ...

Dec 11, 2015 · The differences between grey cast iron and white cast iron emerge from the composition and the color of the surface of the material after fracturing. Both of these iron casting alloys mainly contain carbon and silicon, but in different proportions. A key difference between grey cast iron and white cast iron is that after fracturing, white cast iron gives a white coloured crack surface and grey cast iron produces a grey coloured fractured surface.

Different Types Of Cast Iron | White cast iron, Grey cast ...

The resultant cast iron has properties that vary from both grey and white cast iron. In case of malleable cast iron, the graphite structure is formed into irregularly shaped spheroidal particles rather than flakes that are usually present in gray cast iron. This make the malleable cast iron behave like low-carbon steel.

White Cast Iron - an overview | ScienceDirect Topics

Grey Cast Iron 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. As the name suggests, cast iron is very fluid when molten and is therefore suitable for the manufacture of intricate castings.

Cast Iron: Properties, Processing and Applications - Matmatch

The presence of carbon in this form, as opposed to graphite, is the result of a lower silicon content compared to grey cast iron. White cast iron typically contains 1.8 wt.% – 3.6 wt.% carbon, 0.5 wt.% – 1.9 wt.% silicon and 1.0 wt.% – 2.0 wt.% manganese. White cast irons are extremely wear-resistant yet brittle.

Cast Iron VS Malleable Iron: What's the Difference?

Grey cast iron is the most commonly used cast iron and is the most widely used cast material due to the weight. Grey cast iron's strength is comparable to low or medium carbon steel, but it has less tensile strength and shock resistance compared to steel. Common items made from grey cast iron are well caps and well seals. White Cast Iron. White cast iron was used in both cast iron and malleable iron fittings. White cast iron has a presence of cement that gives off a white surface, hence the ...
