If a particular Fe-C alloy contains less than 0.83% carbon, it is called

A) High speed steel B) Hypo eutectoid steel C) Hyper eutectoid steel D) Cast iron

Discuss

Answer & Solution

Answer: Option B

Solution:

If a particular Fe-C alloy contains less than 0.83% carbon, it is categorized as hypo eutectoid steel. In metallurgy, the carbon content in steel alloys determines their properties and classifications. Hypo eutectoid steel has a carbon content below the eutectoid composition (0.83% carbon) and exhibits specific mechanical and thermal properties suited for various applications in manufacturing and production technology.
