What is the typical carbon content range in high carbon steel?
-
A.
0.1% to 0.3%
-
B.
2.0% to 4.0%
-
C.
0.01% to 0.1%
-
D.
0.6% to 1.5%
Correct Answer:
D. 0.6% to 1.5%
Explanation:
High carbon steel typically contains a carbon content ranging from 0.6% to 1.5%. This elevated carbon concentration significantly increases the material's hardness and tensile strength compared to low or medium carbon steels. Because of these properties, high carbon steel is exceptionally wear-resistant and ideal for manufacturing heavy-duty tools such as drills, taps, hammers, and springs. However, the higher carbon levels also make the steel more brittle and less ductile, requiring specific heat treatments like tempering to achieve the desired balance of toughness and hardness for industrial applications.
