Percentage of carbon in the steels is nearly

Options

A. `3%`
B. `2%`
C. `0.2%`
D. `10%`

Answer

To determine the percentage of carbon in steel, we can follow these steps:

### Step-by-Step Solution

1. **Understanding Steel Composition**:
- Steel is an alloy primarily composed of iron (Fe), carbon (C), and sometimes other elements like chromium (Cr), manganese (Mn), and nickel (Ni).

2. **Identifying the Main Components**:
- The main component of steel is iron, which constitutes about 85% to 88% of the alloy.
- Chromium is also a significant component, typically making up about 10.5% of the alloy.

3. **Focusing on Carbon Content**:
- The carbon content in steel is generally less than 2%. This is a crucial point since the question specifically asks for the percentage of carbon.

4. **Selecting the Correct Answer**:
- Given the options: 3%, 2%, 0.2%, and 10%, we can analyze them based on the information we have:
- Since carbon is less than 2%, the closest and most accurate option is **2%**.

5. **Conclusion**:
- Therefore, the percentage of carbon in steel is nearly **2%**.

### Final Answer:
The percentage of carbon in steel is nearly **2%**.
