Hot Rolled Steel Sheet Properties

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.

Hot rolled steel sheet properties. High strength and highly formable hr steel sheet and plate is also easy to drill form and weld. Hot rolled steel sheet and plate provides a rougher surface than cold rolled steel and plate. Sheets hot rolled steel sheets. A hot rolled steel sheet is made by a steel plate.

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. 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 annealing and or tempers rolling. Jfe steel corporation who holds iso 9001 qs 9000 and iso 14001 certifications produces a wide range of hot rolled steel sheets at the world s strongest and most efficient integrated steel works. 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.

It plays a big role in the type of steel plate. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. When galvanized it is also regularly used in applications where corrosion resistance is a necessity.
