One of the most popular way to make permanent and quality components are through casting. Casting allows a higher level of detail, resulting in no need for further fabrication or assembly. While many different materials can be casts, steel and iron are two of the most popular for most applications due to their excellent mechanical properties.
Cast iron generally refers to gray iron, ductile iron, and malleable iron, which is an iron casting with a carbon content of more than 2%. Cast steel generally refers to ordinary carbon steel and alloy steel, which is a steel casting with carbons contents of less than 2%. Therefore, there is no major difference between chemical content and raw material for cast iron vs cast steel.
