A steel with 1.0 % carbon is known as which one of the following: (a) eutectoid, (b) hypoeutectoid, (c) hypereutectoid, or (d) wrought iron?

Option c)

Explanation:

a. The carbon content of eutectoid steel, which is an carbon - iron alloy, is in between 0.80-0.83%

b. In hypoeutectoid steel, the carbon composition is less than 0.80% and is approximately 0.76%

c. In hypereutectoid steel, the carbon composition ranges from 0.80% - 2.0%

d. In wrought iron, the iron composition is quite low about 0.08%
