Question

What is the purpose of annealing in steel?

1) To add cutting ability

2) To increase wear resistance

3) To relieve the internal stress

4) To refine the grain structure of the steel

​

Answer 1

Answer:

Annealing is a heat treatment process which alters the microstructure of a material to change its mechanical or electrical properties. Typically, in steels, annealing is used to reduce hardness, increase ductility and help eliminate internal stresses.
