Normalizing involvesĀ heating the steel to an elevated temperature, followed by slow cooling to room temperature. The heating and slow cooling changes the microstructure of the steel. This reduces the hardness of the steel and will increase its ductility.

Normalizing raises yield point, ultimate tensile strength & impact strength in steels.

Actually, normalizing improves mechanical and electrical properties. It also removes strains produced by cold working. So, it can be said with surety that it increases ductility.

How if ultimate tensile strength increases then ductility decreases?

Kumar harsh vardhan said:   1 decade ago
How does ductility decreases?

Kunal said:   1 decade ago
B & D are contradictory.

Shek said:   10 years ago
Comparatively option B i.e. ductility decreases during normalizing process.

Abhikant said:   10 years ago
Ductlity increases in normalizing. It decreases as compared to annealed steel.

What is the right answer?

RINI said:   10 years ago
C is the answer because in normalizing temperature increases displacement of atomic planes is easily produces plastic strain easily ductility increases, ultimate tensile strength increases.
