Question

Cold rolling process only affects the tensile strength of the material which being rolled.

(a) True

(b) False

I got this question in my homework.

Question is from Cold Rolling in chapter Mechanical Working of Metals of Casting-Forming-Welding II

Answer 1

Correct option is (b) False

Best explanation: Cold rolling process is a very important process because it allows altering of desired mechanical properties of the material. Cold rolling not only affects the tensile strength, but it also affects the hardness, yield strength, tensile strength and ductility of the material. This process is very economical as the heating cost is excluded from the process.
