Corrosion resisting properties of cast iron are significantly improved by the addition of 12 - 15% of___________________?
Correct answer: C. Silicon
- A. Tungsten
- B. Vanadium
- C. Silicon
- D. All A., B. & C.
Explanation
Adding about 12 to 15% silicon produces a high-silicon cast iron with much better resistance to acids and other corrosive environments. Tungsten and vanadium improve other properties but are not the standard corrosion-resistance addition here.
