Q. What happens to the tensile strength on removal of carbon in carbon steels?

A
Increases
B
Reduces
C
No change
D
None of the mentioned
Solution:

Carbon steel is an alloy of iron and carbon. Low alloy steel includes carbon and small additions of other alloying elements such as chromium, manganese, molybdenum, etc. up to maximum of 5% total added alloying content.

It was observed that the higher carbon content results in an increase in yield stress and ultimate tensile stress, while the elongation remains essentially constant.
