Hot Rolled vs Cold Rolled Steel

Cold rolled steel is stored and sold in coiled form after rolling. Steel comes in many grades, specifications, shapes, and finishes—the World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more applications.

Difference Between Hot Rolled Steel vs Cold Rolled Steel

Typically, mills take hot rolled steel after it's mostly or completely cooled and work it to its final dimension by either rolling it, extruding it, or drawing the metal over a mandrel. For this reason, it's usually referred to as "cold finished" in the industry instead of "cold rolled".

The Differences Between Hot and Cold Rolled Steel

NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000 F.

Rolling Mills

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold
