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. Difference Between Iron and Cast Iron Compare the Feb 07, 2011 · White cast iron is so named because of the fact that its surface is white when fractured. On the other hand grey cast iron is named after its grey fractured structure. Iron on the other hand is the most common metal available in the pure form in
Dec 15, 2009 · For instance, white cast iron is named so because of its white fractured surface, which is brought by its carbide impurities that allow cracks to go straight through. Grey cast iron as well is named so because of its grey surface when fractured, brought about due to the deflection of passing crack by graphitic flakes, which, as the material breaks, initiate countless new cracks. Differences Between Malleable Iron & Cast Iron Iron Although they both contain iron, there is a major difference between malleable iron and cast iron. The main difference being that malleable iron is, well, malleable and cast iron is not. But there are other differences as well. Well need to talk about what exactly these metals are and how they are made.
Malleable cast iron is basically white iron that undergoes heat treatment to convert the carbide into graphite. 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. Ductile Iron vs Cast Iron - Civil/Environmental Dec 28, 2012 · It comprises predominantly a gray cast iron tube and was frequently used uncoated, although later coatings and linings reduced corrosion and improve hydraulics. Cast iron pipe was superseded by ductile iron pipe, which is a direct development, with most existing manufacturing plants transitioning to the new material during the 1970s and 1980s.
Gray iron is also better at vibration damping. The differences are due to the microstructures of graphite within these iron alloys. Gray cast iron is 2.54% carbon and 13% silicon by weight. The silicon in the alloy is necessary to stabilize the graphite molecules that give gray cast iron its properties. How to Tell Ductile Pipe From Cast Iron Pipe HunkerThe difference between cast iron and ductile iron is the graphite form. In ductile iron, the graphite form is spheroidal, or nodular; in cast iron, it is in a flake form. The spheroidal or nodular form of graphite found in ductile iron is accomplished by adding an inoculant, usually magnesium, to the molten iron during the manufacture process.
Common types of cast iron that can be produced include white cast iron, gray cast iron, nodular cast iron, ductile cast iron, malleable cast iron, and compacted graphite cast iron. 2.
