_____________ is added in low carbon steel to raise its yield point?
Correct answer: D. Manganese
- A. Sulphur
- B. Phosphorous
- C. Silicon
- D. Manganese
Explanation
Manganese strengthens low-carbon steel and raises its yield point, while also combining with sulphur to reduce harmful iron sulphide effects. Sulphur itself generally harms ductility rather than improving the yield point.
