The presence of Si in steel gives it

Options

A. Fibrous structure
B. Silicate type structure
C. Sheet type structure
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of Silicon (Si) in Steel:**
- Silicon is an important alloying element in steel. It is often added to improve certain properties of the steel.

2. **Effects of Silicon on Steel:**
- The presence of silicon in steel enhances its strength. This is because silicon can improve the tensile strength of the steel, making it more resistant to deformation under stress.
- Additionally, silicon contributes to the hardness of steel. Hardness is a measure of a material's resistance to localized plastic deformation, and silicon helps in achieving a harder steel structure.

3. **Conclusion:**
- Therefore, the presence of silicon (Si) in steel gives it increased strength and hardness, making it suitable for various applications where durability and resistance to wear are essential.

**Final Answer:**
The presence of Si in steel gives it increased strength and hardness.
