Manganese is added in low carbon steel to

A. Make the steel tougher and harder

B. Raise the yield point

C. Make the steel ductile and of good bending qualities

D. All of the above

Answer: Option C

Solution(By Examveda Team)

The effect of manganese in improving the mechanical properties of steel depends on its carbon content. Manganese also reduces the critical cooling rate during hardening, meaning it increases the hardenability of steel. Its effect on hardenability is higher than other alloying elements. Hadfield steel is recognized for its ability to be work-hardened due to the addition of 10% to 14% of manganese.
