Correct answer: B. Carbon
- A. Manganese
- B. Carbon
- C. Phosphorous
- D. Silicon
Explanation
Carbon has the strongest overall influence on steel hardness, strength, ductility and weldability because it changes the phases and microstructure formed during cooling. Manganese, silicon and phosphorus are important alloying or impurity elements, but their effects are generally secondary to carbon's.
