'Semi steel' is__________________?
Correct answer: C. Both A. and B.
- A. Produced by adding 10-20% steel to the cupola charge
- B. Stronger than cast iron
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Semi-steel is made by adding steel scrap, commonly about 10–20%, to the cupola charge. Its lower carbon content gives it greater strength than ordinary cast iron, so both statements apply.
