Answer:
The statement is True.
Step-by-step explanation:
Steel and cast iron are made up of similar material but the composition of iron and carbon in both are different.
Carbon steel contains 99% iron and only 1% carbon while Cast iron contains 97% iron and 3% carbon.
Thus, steel has lower carbon percentage than cast iron.
However, this minute difference in the composition of both the materials makes a very big difference in the properties of both materials. That's why, Cast iron is more brittle than steel.
Thus, the given statement is true.
