Hot rolled sheet metal properties.

Hot rolled steel is ideal for products where tight tolerances are not required. The steel cools at room temperature. Basic difference between hot rolled and cold rolled steel is the way they are processed. Hot rolled steel is steel that has been roll pressed at very high temperatures.

Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish. No cut fees no minimums and fast delivery or online order pickup from 6 warehouses nationwide. Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering. When galvanized it is also regularly used in applications where corrosion resistance is a necessity.

A heat that typically exceeds 1000 f. Hot rolled steel hot rolling is a mill process which involves rolling the steel at a high temperature typically at a temperature over 1700 f which is above the steel s recrystallization temperature. Hot rolled steel is steel that has been roll pressed at very high temperatures over 1 700 f which is above the re crystallization temperature for most steels. Hot roll our large hot roll steel stock is available in various shapes and alloys with full sizes available.

Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. Most of the steel is rolled in hot rolled. Hot rolled steel properties as it is easy to form metal in high temperatures without any extra delays it is possible to produce it in larger quantities than cold rolled steel. High strength and highly formable hr steel sheet and plate is also easy to drill form and weld.

In this article we will compare hot rolled vs cold rolled steel sheets. When steel is above the recrystallization temperature it can be shaped and formed easily and the steel can be made in much larger sizes. However in certain instances non metallic inclusions will impart some directionality and workpieces less than 20 mm 0 79 in thick often have some directional properties. This keeps the market price of hot rolled steel lower.

Cold rolled has sharper corners and more precise dimensions than hot rolled. Buy online or contact us for a quote. Hot rolled steel hot rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature. Hot rolled metals generally have little directionality in their mechanical properties and deformation induced residual stresses.

Due to the high temperature the surface of hot rolled steel produces a layer of oxidation sheet thus has certain corrosion resistance can be stored in the open air.
