Percentage of carbon content in mild steel is
A. Less than 0.25
B. Between 0.25 and 0.7
C. Between 0.7 and 1.5
D. Greater than 1.5
Answer: Option A
Solution (By Examveda Team)
Mild steel is a type of steel that is known for its ductility and weldability.One of the key factors determining the properties of steel is its carbon content.
A higher carbon content makes steel harder and stronger but also more brittle.
Mild steel has a relatively low carbon content, making it a good choice for applications where toughness and formability are important.
The question asks about the percentage of carbon in mild steel.
Option A: Less than 0.25% is the correct answer because this range defines the carbon content of mild steel.
Option B, C, and D represent higher carbon content, leading to different types of steel with different properties (like medium carbon steel or high carbon steel).
