Hot-rolled steel is weaker than cold-rolled, but it's also cheaper since it doesn't go through the second production process. However, this doesn't automatically mean cold is better just because it's stronger and more expensive. The more significant difference in how to use it is how specific your material needs are.

The classification of hot-rolled or cold-rolled steel depends on the temperature of the metal while it is being rolled. In hot-rolled steel welding, the metal is heated to a temperature so high that it cannot be recrystallized. In cold-rolled steel welding, the temperature of the metal during the process is below the recrystallization temperature.
