Cold Rolled Vs Hot Rolled Steel Plate

The rolls induce plastic deformation.

Cold rolled vs hot rolled steel plate.

References mid city steel. Hot rolled steel vs. Hot rolled steel involves rolling the steel at high temperatures where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by. Hot rolled and cold rolled are the process of steel plate or profile forming.

Hot rolled steel vs. They have a great influence on the structure and performance of steel. Cold rolled steela rolling process at temperatures that. 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.

Industrial metal supply stocks hot rolled steel in the form of structural shapes bar sheet or plate as well as cold rolled steel structural shapes sheet and plate. However this doesn t automatically mean cold is better just because it s stronger and more expensive. The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill and not the product specification or grade. In general cold rolled and cold formed steel costs more than hot rolled steel because of the extra processing steps.

It is also used to produce sheet metal. As an example a hot rolled steel product may have a yield strength of 235 mpa. Cold rolling is done when the metal is able to form new grains as the old ones are deformed by rolling and bending the metal. Cold rolled steel the difference between hot rolled and cold rolled steel is this recrystallization point.

Hot rolled steel is weaker than cold rolled but it s also cheaper since it doesn t go through the second production process. The pros and cons of hot rolled steel come down to strength versus price. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. The rolling of steel is mainly hot rolling and cold rolling is usually used only for the production of steel with precise sizes such as small sized section steel and thin plates.

Cold rolled steel is also up to 20 percent stronger than hot rolled steel making it ideal for parts that require minimal mechanical fluctuation under pressure. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. Cold rolled steel is stored and sold in coiled form after rolling. The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications.
