Hot-Rolled Steel vs. Cold-Rolled Steel

Mar 27, 2020The pros and cons of hot-rolled steel come down to strength versus price. Hot-rolled steel is weaker than cold-rolled, but its also cheaper since it doesnt go through the second production process. However, this doesn't automatically mean cold is Images of Bright Spheroidize Annealing Cold Rolled Steel Strip imagesAnnealing of Cold Rolled Steel Steel WarehouseAnnealing recrystallizes the grain structure restoring ductility so the material can adequately bend for its intended application. Higher temperature longer cycle time annealing can be used to make medium and high carbon steels extra soft by spheroidization.
