Which of the following is soft in nature?

Right Answer is:

Coarse pearlite

SOLUTION

Coarse pearlite forms upon annealing which makes them possess greater interlamellar spaced ferrite and cementite when compared with, fine pearlite which forms upon normalizing eutectoid steel.

In the spheroidal or nonlamellar structures, the same is true; coarse spheroidite, or spheroidized pearlite, is much softer than the barely resolvable structures resulting from the tempering of martensite, generally known as sorbite.
