How is cast iron different from steel?

Answer 1

Steel is different from cast iron because cast iron is when some of the molten iron is left to solidify in moulds. And then most of the iron is kept molten to be turned into steel. But steel is made by removing move of the impurities from the iron and then mixing other elements to change the properties.

Answer 2

1) Cast iron is iron in its pure form whereas steel is an alloy.

2) CI is strong in compression and weak in tension. Reverse is true for steel.

3) Workability is better in the case of steel than CI because of elongation properties.

4) CI is brittle whereas steel is ductile.
