Hot Forging A forging process in which metal is recrystallized above the temperature.

Hot rolling The process of rolling at temperatures above recrystallization.

Cold rolling process in which the plastic deformation temperature is lower than the recovery temperature.

Annealing: Process in which metals are heated slowly to a certain temperature, for sufficient time, and then cooled (usually slowly and sometimes controlled) at a suitable rate.

Pickling: Immerse the product in an aqueous solution, such as sulfuric acid, to remove oxides and other thin films on the metal surface. Is electroplating, enamel, rolling and other processes of pre-treatment or intermediate treatment
