White cast iron is the hardest type of cast iron which is due to presence of carbon in the form of iron carbide or cementite
note: cementite is more harder since it has highest percentage of carbon in it(6.7%).carbon content cannot exceed 6.7% because on further increase in the composition of carbon would not combine with iron

White cast iron is formed when most of the carbon content in the alloy forms iron carbide.
White cast iron is a type of cast iron that is characterized by its white, brittle structure. This type of cast iron contains carbon in the form of iron carbide instead of graphite, unlike other types of cast iron.
Iron Carbide Formation:
Iron carbide, also known as cementite (Fe3C), is a compound that forms when carbon atoms combine with iron atoms in the alloy. In white cast iron, most of the carbon content in the alloy forms iron carbide. This results in a white, hard structure with little to no graphite present.
Properties of White Cast Iron:
1. Hardness: White cast iron is known for its high hardness due to the presence of iron carbide.
2. Brittle: White cast iron is brittle compared to other types of cast iron, making it less ductile and more prone to fracture.
3. Wear Resistance: The hardness of white cast iron gives it excellent wear resistance, making it suitable for applications where abrasion resistance is crucial.
Applications:
White cast iron is used in applications where high wear resistance is required, such as in the manufacturing of grinding balls, liners for grinding mills, and certain types of rolls.
In conclusion, white cast iron is formed when most of the carbon content in the alloy forms iron carbide, resulting in a white, hard structure with unique properties suited for specific applications requiring high wear resistance.
