Cold working of metal increases

A. Tensile strength

B. Yield strength

C. Hardness

D. All of these

Answer: Option D

Solution(By Examveda Team)

An example of desirable work hardening is that which occurs in metalworking processes that intentionally induce plastic deformation to exact a shape change. These processes are known as cold working or cold forming processes.
The cold working of the metal increases the hardness, yield strength and tensile strength.
