WebMar 26, 2024 · Chill casting is produced by inserting metal plate inside the sand mold for extracting fast heat from a composition containing a high amount of silicon to cause graphitization in the rest of iron. This results in a white shell and grey core containing high hardness and toughness.
WebGray cast iron is the oldest and most common type of cast iron. Gray cast iron is characterised by its graphitic microstructure, which causes fractures of the material to have a gray appearance. This is due to the presence of graphite in its composition. In gray cast iron the graphite forms as flakes, taking on a three dimensional geometry.
