WebMar 21, 2024 · One unique characteristic of Cast Iron type is that it is only a unique unit of cast iron with carbon present in the form of carbide. In the rest of the cast irons, carbon as a separate identity is present as well. Why it’s called White cast iron? White cast iron consists of carbides and pearlite. Carbides are extremely hard and brittle. WebThe difference between iron, steel, and cast iron is the amount of carbon present in the material. Pure iron does not have any carbon, steel is any iron alloy with up to 2 weight percent (wt%) carbon, and cast iron is any iron alloy with more than 2 wt% carbon. In practice, iron alloys will rarely have more than 4 wt% carbon.
