Manganese in steel increases its

A.
Tensile strength
Answer
B.
Hardness
C.
Ductility
D.
Fluidity

Answer: Option A

Solution

Answer: Option A
Solution:
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
