Very high sulphur in pig iron makes ___________________?
Correct answer: D. Its casting unsound
- A. All A., B. & C.
- B. Its hard and machinable
- C. Its brittle and malleable
- D. Its casting unsound
Explanation
Excess sulphur in pig iron promotes brittleness and causes hot-shortness, so castings may crack or become unsound. It does not make the iron both hard and machinable or brittle and malleable.
