Cold rolling is a process by which metal is passed through rollers at temperatures below its recrystallization temperatures. The metal is compressed and squeezed, increasing the yield strength and hardness of the metal. Cold rolling of metal strip is a special segment within the metalworking industry.

How does cold rolling work?

Cold rolling is a process which passes metal through rollers at temperatures below its recrystallization temperatures. This increases the yield strength and hardness of the metal. This is done by introducing defects into the crystal structure of the metal creating a hardened microstructure which prevents further slip.

What is cold rolling used for?

In simple terms, cold rolling is an industrial process used to change the material properties of sheets or strips of metal. The metal is fed between two rollers which compresses it.
