The percentage of carbon in low carbon steel is
A. 0.05%
B. 0.15%
C. 0.3%
D. 0.5%
Answer: Option B
Solution (By Examveda Team)
Steel is an alloy (a mixture) of iron and carbon.The amount of carbon in the steel greatly affects its properties like strength and hardness.
Low carbon steel, also known as mild steel, has a relatively low percentage of carbon.
Lower carbon content makes the steel more ductile (easier to bend) and weldable.
Let's look at the carbon ranges for different types of steel:
* Low Carbon Steel: Typically contains 0.05% to 0.25% carbon.
* Medium Carbon Steel: Typically contains 0.25% to 0.60% carbon.
* High Carbon Steel: Typically contains 0.60% to 1.00% carbon.
Therefore, of the choices given, 0.15% falls within the range for low carbon steel.

C
Low carbon steel contain less than 0.3% carbon so given answer is correct
Low carbon steel :- 0.3% to below
Dead mild steel :- 0.15% to below
So right answer is C
