Annealing ofwhite cast iron produces __________ iron.

ANS:C - malleable

Annealing of white cast iron produces malleable iron. Annealing is a heat treatment process that involves heating a material to a specific temperature and then cooling it slowly to modify its properties. In the case of white cast iron, which is hard and brittle due to the presence of cementite (iron carbide), annealing causes the decomposition of cementite into graphite flakes. This transformation results in malleable iron, which is softer and more ductile than white cast iron, making it easier to machine and shape.
