Hot Rolled Steel Vs. Cold Rolled Steel Sciencing

Apr 24, 2017 · The steel is then allowed to cool slowly to room temperature in still air. This annealing process recrystallizes the steel for greater ductility, but because the steel is worked at room temperature, it maintains its strength. Working cold-rolled steel is much more difficult than working hot-rolled steel, so only basic shapes are possible.

Hot Rolled vs Cold Rolled Steel Metal Casting Blog

Cold rolled steel is essentially hot rolled steel that has been through further processing. Once hot rolled steel has cooled, it is then re-rolled at room temperature to achieve more exact dimensions and better surface qualities. Cold “rolled” steel is often used to describe a range of finishing processes, though technically “cold rolled” applies only to sheets that undergo compression between rollers.
