High Strength Cold Drawn Steel Bars
The first feature is size. Comparing to a hot rolled bar, which is formed (rolled) at high temperatures, a hot rolled bar will vary greatly in size, with a larger variance the bigger the diameter. Hot rolled bars will also have an oval or eggy-shape to it. Roundness on a cold finished bar will coincide with size, being half the size tolerance.

Hot Rolled vs Cold Rolled Steel | Metal Casting Blog
Cold worked steels are typically harder and stronger than standard hot rolled steels. 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.
Hot Rolled Steel vs. Cold Rolled Steel
Greater strength: Cold rolled steel can exhibit strength up to 20% greater than that of hot rolled steel, which makes it more suitable for use in high-stress applications. Better surface finishes: Parts and products made from cold rolled steel generally have a smooth and shiny surface that is free of rust and scale.
Hot Rolled Steel Vs. Cold Rolled Steel
These metals don't differ in product specification or grade; rather, different processes are used at the mill to create the two materials. Hot rolled steel involves rolling steel at high temperatures, while cold rolled steel refers to processes done at or near room temperature. Certain types of steel will work better with certain applications ...
Cold Rolled Steel Bar
Cold finished steel is essentially hot rolled steel that has further processing. Cold finished steel, also known as cold rolled steel, is typically produced as turned bars or cold drawn bars. Cold drawing hot rolled bars is accomplished by pulling (drawing) a bar through a die which is smaller than the incoming hot rolled size. The cold working process improves …
