Wrought iron is having very high ________________?
Correct answer: C. Corrosion resistance
- A. Hardness
- B. Strength
- C. Corrosion resistance
- D. Susceptibility to changes in its properties by heat treatment
Explanation
Wrought iron contains very little carbon and its fibrous slag structure gives it good resistance to atmospheric corrosion. It is relatively soft and weak compared with steels, so hardness and strength are not the best choices.
