If a particular Fe-C alloy contains less than 0.83?rbon, it is called
Answer: B
The carbon alloy having less than 2?rbon are called “steels” and those containing over 2?rbon are called cast irons. Now, steel may further be classified into two groups.
(i) Steels having less than 0.83?rbon are called “hypo-eutectoid steels”
(ii) Those having more than 0.83?rbon called “hyper-eutectoid steels”
