Cold Rolled Vs Hot Rolled Steel Plate

Cold rolled steel is stored and sold in coiled form after rolling.

Cold rolled vs hot rolled steel plate.

Hot rolled and cold rolled are the process of steel plate or profile forming. This makes hot rolled steel a good choice for the manufacturing of structural components such as i beams or simple cross sections such as rail tracks. As an example a hot rolled steel product may have a yield strength of 235 mpa. Cold rolled steela rolling process at temperatures that.

References mid city steel. Cold rolled steel the difference between hot rolled and cold rolled steel is this recrystallization point. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. As noted in an earlier post different types of steel undergo a wide range of processes to achieve the proper physical properties many people have heard that there s a difference between hot and cold rolled steel but don t understand what how the production of hot rolled or cold rolled steel is different from one another what industries and applications hot rolled and cold rolled serve.

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. 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. 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. Hot rolled steel vs.

They have a great influence on the structure and performance of steel. 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. It is also used to produce sheet metal. In general cold rolled and cold formed steel costs more than hot rolled steel because of the extra processing steps.

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. The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications. 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. Hot rolled steel is weaker than cold rolled but it s also cheaper since it doesn t go through the second production process.

The rolls induce plastic deformation. 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. Hot rolled steel is more malleable allowing it to be forced into a variety of different shapes. Hot rolled steel vs.
